I have absolutely no idea if she's cheating and if she is, I can guarantee you it's not with me. As for what to do next, well, I'm just as lost on that

This is some back information... I've been with my girlfriend for almost a year now and some recent information made me very worried. We talk about getting married all the time and have a overall good relationship. I don't think i've done anything to her at all or treat her bad. I help her with a lot. I do trust her but some things don't fully add up... My co-worker told me (someone that i don't really like and he has made it clear he doesn't like me) my girlfriend cheated on me. He said she kissed two guys at a club while she was drunk. He then called another guy (who i don't know or trust) who said he saw her kissing two guys at another club. I asked her about this and she swears up and down she did not cheat on me. I believe her when she tells me, i see it in her face... i hope. But i have this nagging, worried feeling everytime i think about it. I just don't want to blow this off because i just might be blined by love to see the truth... but i don't want to drag it out if nothing happened, just further damaging the relationship. My co-worker pulled me aside a few times and told me piece by piece, twice while we were drunk. I don't know what to think about this. He does sound convincing but I don't trust him. Times and dates add up, but i don't know. She was with her friend the whole time... who said she didn't do anything (but thats her friend). Any imput would help, i'm just really confused. Thank you I am updating my situation here... any more imput would be nice.. I did confront her already, she says its not true. Its been a couple of days since the first talk, but many keep coming up. She still says its not true and i think i believe her. I'm like 95% sure but still have that doubt, just because i don't want to mary someone who has cheated on me. I would think that after a few talks she would admit it, or shes too deep in her lies to pull it all back now. I never had a problem with this before, i have never acted jelous, made her feel like she can't hang out with her friends or go out. I can't be in a relationship with someone who i can't trust. Thats why i let her do whatever she wanted. But going out to a club, drinking, agressive guy might just be a bad place for an attractive 21 year old girl. If she did cheat on me then she only did it cuz of drinking and she just kissed a guy or two. I don't think she would do it again, if she did. So i just wonder what i'm supposed to do from here. There is no real proff either way but i still need to know the truth. Something solid. That guy didn't tell me something solid but he at least had a few sorces. I did trust her fully, i still do trust her, but i am just paraniod now. What should i do???? Another update... Its been two weeks since everything went down. There has been many talks about the situation and she says its not true. She has been spending more time with me and doing more nice things. Should i just drop the whole thing and believe her 100% or try to find more answers? It seems like she really didn't do it, but i have some doubts... i just don't understand why someone would lie about something like that. I never did anything bad to this guy. Should i just stay with her and not worry about it?? Thanks

i think that you should teach her a lesson by makin another girlfrnd in kissin in front of her... she will really get d lesson

Ask him to take a picture next time. You don't even like this guy and don't even know if you trust him. Why would you rely on him for evidence?

Must have missed the lot of info part here...Do what any paranoid red blooded man would do, check her panties for skid marks, follow her, scour her cell phone records, corner her and accuse her of cheating and watch her reaction, hire a private investigator and give her a polygraph while you are at it. Then you'll have your answer.

I read all your background information and here is what it says in a nutshell: A person you neither like nor trust told you one thing. Your girlfriend whom you love and trust contradicted that. Believe your girlfriend, drop this issue and stop talking to the asshole you work with, except for work related issues.

i would beleive her totally, if the co worker doesnt like u then wouldnt he try and make ur life hell?? u should always trust ur significant other over a co worker (unless their like family)but anyways i would drop the whole thing and if it did happen again i would find out exactly what happened. then if she did actually cheat i would dump her, no one deserves to be cheated on(i've been cheated on b4)

I see absolutely no reason for you not to believe her. I mean, you only heard this from a guy you don't even trust.

You've come across the greatest problem i've ever experienced. The difference between mine and yours though is that in my case it wasn't a friend who told me these things. You are in the position where you want to trust her but can't due to what you've been told by a third party. This is my advice to you and it's what I would do in your position.... You have no proof, just heresay. people will tell you things which aren't true for whatever reason. I don't understand it myself. I don't play games with people so I can't follow the thought process. It seems to me like your co-worker and his friend are playing you for a fool. You have no reason to trust them. I'd tell them, basically, to screw off. As far as your girlfriend, I'd have just one more talk with her and make it very clear what you expect in the relationship. My guess is that she's been totally honest and faithful.... you will never really know the absolute truth but she seems real to me. I'd tell her that I've told these guys to screw off and that I want to clear the air and move on. I'd just make it clear what I expect from her and drop it for good. Like I said, based on what you're saying, that's what I'd probably do. I hope you work this out. Good luck.

You don't like OR trust the guy who told you this. You love and trust your girlfriend...(or you did before this guy planted some doubts.) The guy either is interested in your girlfriend, or he hates the fact that you have a good one. People like to start shit...Don't let him be the reason for your break up. Drop it...if she were cheating, there would be signs.
