Relationship falling apart!!

I need some serious advise, I have been in a relationship for almost five years now, in the beginning I was the one who really pursued this relationship, I was crazy in love with him. He’s my best friend and we usually get along well, laughing and joking but the relationship seems to be falling apart and has been for a while. We have been through a lot in five years, including an affair he had with a friend of mine, I forgave and we worked through it as much as we could, but I still have a lot of anger towards him and I have a difficult time trusting him. I truly love him, but I feel that I am becoming resentful and bitter, I get annoyed by him easily and I am to quick to start judging him and screaming at him. I’ve stopped communicating because I feel like he doesn’t listen to me or if he does listen he confuses what I am saying. I also feel that I’m becoming resentful because I’ve really helped this guy out, emotional, financially, I’ve gone out of my way to help him and I feel like he takes me for granted, and doesn’t return the favor. Our relationship is a one way street, that I can’t even get on.

Were very different people, not that it’s a bad thing but after five years I beginning to see this differences more clearly. I’m very independent and a bit of a loner, while he is far from being a loner and can be quite needy and insecure. I feel like I’m this really unpleasant person to be around, I guess I’m just done with the fighting and arguing. Recently I’ve had an ex-boyfriend contact me through the internet, at first it was just the two of us asking how we have been and catching up, but now he’s telling me how much he still thinks about me after almost six years and how he wants to see me. So for the first time in our relationship I’m actually persuaded to have an affair, I’ve been thinking about it and I feel guilty for it. What really sucks is I don’t really have anyone to talk to, my friends are his friends and everything I say just gets back to him and he freaks out on me. All my friends think we should work it out because were so good together, my family thinks I should end it and I have no clue. I know that he wants us to marry someday and start a family, but I am not ready for that, I’m not even ready to live with him, I guess I have commitment issues but I don’t know if he’s the one.

Please help… I need some good solid advise, any would be helpful, thanks.

ok.... Where to begin??? 1st of all, don't cheat... If you aint caring 'bout him anymore then break up with him... but dont cheat... you will just kick yourself in the ass. Why? well because your ex man is calling after 6 years and justs wants to have some fun.... What he thinks 'bout you? It could be true, but he just wants 2 have fun for a little while. And since you and your man aren't in good terms @ the moment it's a great time for him. But lets say you cheat and your man finds out? your ex kicks you 2 the curb, you got no man because you cheated... So what you got??? nothing.... get it? second.... He cheated on you before??? with your friend? he should had been done long time ago. but remember 2 wrongs dont make a right. 3 of all, LET THAT SON OF A B*TCH GO, WHO HAS NO RESPECT FOR U. and your friend, f**k her aswell. Get me???? Easy as that. you dont need that sh*t. If I was 2 be in your shoes?? I would defenetely feel for him? because, I would chew him up.... Believe that? But I aint got a punk like that. I've got a MAN!!!!! Who knows better. see yah & excuse my language.... thanks for listening,and hope I was a bit of HELP.
