I have been dating this girl for a few months and it took off really fast, to fast where we had to take a break. Now she is a very big flirt and I also work with her, and there is a guy that works with us he is really cool and someone that I can trust. He is also a big flirt so there friendship reloves around flirting, which is fine except that I have to watch it. Now I have talked to both of them about it and told them how much it hurt me. They continue to do it, every time we go on a date he ends up texting her the whole time. Yesterday at work they were even textin each other. She says they are just friends but why does she keep doing this if she never wants to hurt me? Please anyone with some feedback it would be great??

I might be wrong, but it sounds like she just may not want a relationship right now.

So you took a break because it got too serious too soon? If you have already talked to both of them, there is really not much more you can do. If they are not willing to change it, you have to deal with their flirty friendship or move on.

If you took a break you basically gave her a reason to flirt with other men, and I'm not saying she's going to do anything with them or that you do anything with anyone else but you should really take responsibility for not handling it within those first serious months

Apart from that I suggest that you keep a good relationship going with her, flirt and such, and avoid admitting that you're jealous

She might not like the idea of being clung to

Just my opinion, and then again
I'm not very good at this kind've stuff

Sounds like she just wants to be single and talk to whichever guy that she wants. She obviously not ready to settle down with 1 guy. You've got three choices:

1) Continue the way it is and wait around.

2) Step it up and tell her how you feel. See what she says. But chances are, she doesn't want a relationship with you.

3) Forget her completely and move on. Find someone else who actually wants a relationship.
