After four months of the relationship my girlfriend started giving rides to a guy that she knows at work, he would call a lot in the beginning and I told her that I did not like this kind of behavior. Recently, my girlfreind stated that this guy drives a blue car and lives on the north side of town, Well comes to find out that the guy drives a maroon car and lives on the south side of town. Was she cheating.

Well, not necessarily. She could have been or maybe he just moved and got a new vehicle, maybe it's a different guy, or maybe she just didn't tell you because she was worried you would get jealous( not saying you are, or anything, just trying to figure out what might be going on in her head). Don't accuse her yet, but be on the lookout. If it were me, I would just come out and ask her why in the heck she lied. Maybe there is a good explanation for the difference in stories. If not, then it sounds like she is being dishonest for some reason. Maybe some couples counseling might help you guys. Good luck!

Maybe she got it wrong, or you did. Be honest and ask her, assumptions are not facts.

Sounds like you assume a lot and have no basis, if they work togeather, they are probably friends just helping each other out. You need a bit more hard evidence before you accuse people of sleeping around when they are just co-workers giving assistance to help out. :rolleyes: This is something that mature people do often, if she had any forgetfullness of what the car looked like well she probably just saw it from afar and didn't give it too much attention. She probably didn't care what his car looked like and not an important fact to her or to her work. I say your going way out on a limb and shouldn't pass judgement. Are you hiding something you feel bad about?

She could be and couldn't be. You never know. If she starts to act differently, most likely yes. But talk to her about it. Don't be too quick to judge. Get the facts straight first.

Wow, if I assumed my fiancé was cheating every time she got some details wrong I'd be a nutcase with assumptions. Maybe she didn't think it was such a big thing to remember and when you asked her she only recalled what she thought. I get little details mixed up all the time when I tell things to my fiancé, but I'm not cheating.
