My girlfriend (we'll call her Meg) and I have been dating for nearly 3 years now... she and I are both 21...

I have a 3 year old daughter from a previous relationship which ended in divorce and my daughter hasn't seen her father for almost a year now...

Anyway, getting on with the issue at hand: 'Meg' and I moved in together after dating for 6 months... we first had a roommate and then after 3 months of that we got our own place which we lived in for a year and a half. Then I lost my job & we lost the apartment.

Since then, I've been living with my parents about 5 miles from where she is staying with a friend of ours. About 3 months ago we met this girl (we'll call her Betty) and started hanging out with her every once in awhile... now don't get me wrong, she's really nice... and she was straight but bi/curious when we met her... she recently had an experience with a woman and now says she is bisexual.

Now 'Meg' and 'Betty' started hanging out together a lot about 3 1/2 weeks ago... and by a lot I mean any time 'Betty' wasn't at work they were either together or on the phone. Betty even started staying the night with Meg in her bed at our friend's house several nights a week and one night Meg even went to Betty's to spend the night.

All the friends in the house think that they are getting it on behind my back, so we confronted them. They both deny anything happening. But also, both of them have admitted to me that they have feelings for one another...

But then I found one of Meg's shirts in Betty's car with some white stuff on it that happened to look like female... stuff... and then I put that shirt in Meg's laundry which I was to do later that night... took it home... shirt is no where to be found... and the friend Meg is living with helped me go through all of her stuff one night when she was gone and we could not find it AT ALL.

Now Betty went to New York to visit family for 3 weeks... but Meg and Betty are on the phone constantly... talking... texting... irritating the HELL out of me... and I asked them to back off each other a little bit to make me feel less jealous... and they wouldn't listen... which led to me breaking off the relationship with Meg (so she would realize I'm serious about chilling out with this chick) and Betty was angry with me...

Later that week Meg and I were still fighting over all of this... and she still wouldn't stop calling Betty all the time... so I had Meg's cell number changed and didn't give her the number... so Meg and Betty weren't able to talk or text for like 3 days until I eventually gave up that idea just because it was making Meg so angry.

What am I supposed to do? Betty is kind of talking to me but Meg still seems so secretive to me... she says that she needs space to figure out what she wants to do with her life, but that she still loves me very much and doesn't want to lose me. I feel like if she doesn't make a decision fast that I am going to lose my mind... or explode.

I've talked to Betty a little bit about some of these things, and she said that she's not trying to get in the middle of us, but she already caused me to end it with Meg... and that's the last thing I wanted to do... Meg is still showing affection to me and we still have sex every once in awhile... but then these stupid little fights come up between us and it's always sparked by my saying that I don't want Meg & Betty to spend time alone.

Meg has said that she will NOT date a bisexual girl because it makes her uncomfortable, but at the same time she likes her a lot and definitely wants to sleep with her...

Betty is coming home on Saturday... she invited me to come to the airport when she lands, but Meg is going and wants to go alone...

What the hell should I do? Should I stick around and watch Meg slowly leave me for this chick or stay and fight for my woman? I've told Meg that if she was up front about all of this in the beginning and included me in all of this, we could've turned it into a fun thing that we could do together as a couple... and I'd still be into that if she would stop being secretive and just be honest with me.

Meg and I have had a lot of long conversations about everything, we've even talked about being roommates for awhile so that we can both get out of the living situations we're in... the conversations usually go pretty well... there's been crying on both sides and talks of compromise, but it seems like she just doesn't want to compromise on anything regarding Betty...

I know Meg loves me, it just seems like Betty swooped in and ruined our relationship... granted Meg and I have had a few problems & fights over the years, but we were pretty stable until she came around...

What do you think?

I think you weren't as stable as you would like to believe. Doesn't matter if it is a straight relationship, gay or bi-sexual, cheating is cheating. And in the terms of cheating, well sleeping in the same bed for a straight relationship wouldn't fly to well, so don't know why this would be any different. "Meg" has it bad for "Betty" but she wants her cake and wants to eat it to, You being the "cake" Simple, break it off. Til "Meg" can give you her full attention with no interuptions. Seems she likes "Betty" a little more than Betty likes her. Unless Betty is playing games with both of you. I seriously would have no part in it at all. If Betty is playing you and Meg, well if YOU don't play, she will stop because it won't be fun anymore. Then Meg will realize it and then you can sit down and talk. But have you even stopped and thought, why wouldn't Meg want to stop seeing Betty? They haven't been friends that long.. she seriously has a thing for her. I would worry more about your child and your living condition and get back on your feet. Meg doesn't sound like she is really ready to settle down. And being room mates is a bad idea, you would get hurt more than anyone.

There is nothing that sounds stable about this relationship to me. I think at your age and with a child you should be more focused on that then getting involved in stupid high school drama that isn't productive for you or anyone involved.

As the other posters have pointed out, you and Meg were not stable enough to keep a roof over your heads, and that left Betty the opportunity to come and pick up the pieces. Forget it and work on getting you stable, and take care of your child, that should be your top priority.

Finish it with her there is no talking about this tell her and betty to be happy with other and leave you alone. When she no longer has you as the fall back and realises she is losing you then she may spark up. I mean disappear don't just hang around or keep in contact, just get out she will call tell her its not guna workl and she can be happy with the girl you will move on you are not into that. Don't go saying we could all be in it together that's not the way , that's only you trying to keep her. If you really want her the get rid of her
