Maybe he did the best he could and that wasn't enough. In the end, I'm not sure his motives or choices matter. Yours do.

I've gone through some similar feelings (although not online) and it's really nobody's fault. He's not playing you; he's just making the choices he feels he needs to make for his life.

I don't think it's a good idea to try to stay in contact with him. He's made it perfectly clear what he wants. Whether you agree or disagree with his decisions; he has a right to make them for himself. He's doing what he thinks is best for his life.

Let yourself get over this relationship. Mourn it. Remember it. Then let it go. And in future remember (as I frequently have to remind myself): You deserve a whole man. Not just a piece of one.
