Some people still believe in minding their own business.

Some guys do not appreciate what they have until they've lost it.  If he's cheating now, he'll cheat for the rest of his life.  Dump him!  You can do better with someone who does appreciate a good thing when he finds it.

if he cheated while unhappy and attempted to cheat while happy, this guy seems like a serial cheater. some guys are like that. no matter how happy they are in their relationship, they just need attention form other women. you deserve better than this guy.

One word: jealousy. Guys dump girls all the time, yet for some reason, we still feel attached to them. When we see ex-girlfriends enjoying a new relationship, we immediately long for wht we once had. It's just human nature.

some people like to sabotage their relationship by saying things like that so that one day, when you are finally pushed and do cheat or leave him, he can say, "you see, i told you so!"  it's a twisted way of thinking, but it's a defense mechanism like they're preparing themselves for it to happen.  he's obviously been hurt before and he really shouldn't take his frustrations out on you.  all you can do is be open.  those who have nothing to hide, hide nothing.

HORSE HOCKEY The boyfriend in question is guilty of cheating and the reason he will not talk about it, is because he is wondering what gave him away. Be a friend help your girl to move on and get a new boyfriend.

Often because they feel that the girl friend has stolen their friend from them. Imagine it, the guy has his friends, they hang out together all the time, get drunk, pick fights, whatever, they rely on each other and trust each other. Then, all of a sudden, a girl comes along and the guy is dating her. Next thing you know the guy has two demands on his time, his friends' and his girlfriend's. Obviously he could hang out with them both at the same time, but most guys will want to spend time alone with their girlfriend, so that doesn't normally work. The guy will typically end up spending more time with their girlfriend that with their friends because of:\n\n1. Sex, intimacy etc...\n2. The guy won't really know how to keep the girl happy and will want to spend alot of time with her to prove that he likes her and because he's afried she'll dump him if he spends too much time away from her.\n3. It will never occur to the guy that his friends will be jealous, he trusts them and thinks they want the best for him. \n\nAnyways, the guy's friends (because they're *his* friends) are far more likely to blame the girl than the guy for the fact that he spends nowhere near as much time with them anymore, so all the jealousy and frustration gets targetted at her in expressions of contempt and suspicion.\n\nIt should be pointed out that sometimes they're right, the girlfriend feels alienated from the friends and wants the guy alone to herself, so she deliberately sets things up so the guy spends more time with her than with them.

Most guys when they find out that their girlfriends want to talk about their relationship or feelings or whatever, they think that there's a problem or something. Guys are like that, they'd never examine or look into anything at all unless something is wrong with it. Not a lot of guys talk about their relationship with their girlfriend just because they should. It's usually only if there's a serious problem or something, otherwise they'll just think then what is there to talk about ? what is there to say about it ?

Um....so you are asking us this...you are attracted to this guy, who either has a girlfriend and just flirts with you, or is not honest with you.  I'm thinking that he is either considering cheating on his mysterious girlfriend with you and just hasn't the courage yet, or  he just wants to fool around a little without commitments...And he knows that he has you hooked..So if you really want to pursue this...be patient..ignore him and don't be so available....see what happens.

First of all your not the scum he is. If he is cheating on her with you then he will cheat on you with someone else. Since your relationship with him has been sexual I would tell the girlfriend. She has a right to know what she has been exposed to. I am not saying that you have anything but the guy may be seeing several other women and not just you. It is also very common to be angry at the other woman and not yourself or the guy. If you look at this logically then you would see who you should be angry at. For the last two years this guy has been leading you and his girlfriend and God knows who else on. When you found out about the girlfriend you probably thought that he would dump her and stay with you. It doesn't always work that way. If you dont tell her and leave the guy you are always going to be second guessing what he is up to. You are always going to be comparing yourself to his girlfriend and you will never be happy. Telling his girlfriend would only be fair to her. You have known about her and have seen what this guy is like. Maybe his girlfriend needs an eye opener. And the guy deserves to be alone.

I feel for you on this one.......what I've noticed with the one girl that cheated on me is that you stop talking about your feeling for one another and try to hide what he did that night.  The shorter the conversations the more likely it is that the other person is cheating on you........

They do it because they are dumb. I just got out of a realtionship like that and he wants me back. He is a big loser all they want is sex and if you don't give it to them, they WILL cheat. I cryed so much over him...hes a loser

They probably dont want to admit it. Or because they are "ashamed" to admit about their girlfriend that is a stupid guy if a guy is like that.

In my honest opinion....\n\nThe guy didn't technically cheat.  Try to look at it this way, he went out with the girl a few times, and then he realized how much you meant to him. Sometimes it takes being with the wrong person to realize that you are with the right person. In addition there was not touchy feely stuff so he probably wasn't attracted to her in the first place.  He probably just wanted to reassure himself that you were the right girl for him.  Guys get anxious and cold feet too, they just handle it differently than we do.  Talk to him.  Tell him how you feel about it and explain to him that your trust and love is a privilege, and he should be honored to earn it.

Cheating means that you deceive someone you love (hopefully love anyway). If you do it openly they have the option to kick your butt, join in or leave you alone with your new find.\n\nNot telling them is just a cowardly way of lying. Postponing the truth and hoping it won't be found out.
