He says he can't be with me anymore and that I'm never going to change. He says he feels bad like he's always failing and can never meet my expectations. He's sick and tired of feeling like that and although he loves me and wants to be with me, he can't and is not going to anymore. We've had fights like this in the past where we would be able to talk it out and get back together, but this time he's not backing down and is for real. I almost lost him a year ago but was able to inspire him to give us another chance and now he's fed up. I love him we have a son together. I just don't want to argue and bicker anymore. How can we fix this? I don't want to let him go.

He is not able to meet your expectations how, in what?

Lets try to think about this for a second because I am lost like you, okay.

You love him and he loves you, you have a son together, and you survived this fight few years ago. Sounds great so far.
But, I need you really to answer this question above.

Anyway, maybe you are shooting to high, the problem might be with you not him, instead of expecting why don't you accept what is offered?

Still, if he loves you and you both are responsible for the kid, he should not declare that he is quitting during the moment you are fighting. It is really careless of him; He should take these decisions into a deeper consideration, and you should try to go easy not out of pity but to keep this mirage last while you can, this will take the two sided efforts to work. So work it out together.

Remember from your post, you words don't explain how intense this situation is, so I am assuming it could be avoidable. In all cases, this might be your only solution.

If you don't want to argue anymore, then don't.

You give not one clue why you do, so I don't know how we can help.

Too many people assume that because they have broken up before and been given a second chance that they have an unlimited supply of second chances. Not so.

Too many people fight instead of sitting down to work out a plan to solve problems. Doesn't provide support? Hangs out with they guys and leaves you at home? Lies around the house not helping out? Spends money on himself? You don't bicker, you find solutions - together. If that doesn't work, you accept the fact that you can't live together.

Heck of a good post by joypulv. Oops! You must spread some Reputation around before giving it to joypulv again - Gosh I hate that.

Anyway I totally agree with what she said. People get to a point in a relationship where they weigh the good and the bad. In the boyfriend's case, the fighting outweighs the good times he has with you. I don't think you can get him back from everything that you posted. I don't get why some couples rely on their drama for excitement.

You need to make sure this is a good learning experience for you so that your next relationship is not drama filled.
