Heartbreak, Any ideas?

Well I agree with vezna to a point. You need to find out the reason you fight, is it money, social issues, child care issues, or the "i have to have the last word" or " I am never wrong" fight. You also need to take a deep look at yourself and figure out who starts most of the fights. Is it you or him. Lots of people will instantly say the other started it, although you know how to push the others buttons so that he starts it or something to that effect. My ex knew exactly how to push my buttons and start an argument. I knew her buttons as well. Where I don't agree with vezna is the point about going back to a person who walks out. That's just plain dumb. Nobody should stay in a relationship that they truly don't like, or don't feel loved in, and argue all the time for the sake of family. It's not healthy for either party, and it certainly isn't healthy for the child. To be honest, in my opinion, a slight chance is pretty much a no. It's his way of trying to let you down easily. Especially if you guys were talking for a long time and he feels that you wouldn't take no for an answer, or if you were crying a lot, he would probably tell you that to soften things up a bit. To be honest, it may be best to to give him some space, and that way you both could evaluate the situation and see if being together is the best thing for both parties.

Ask yourself why he is leaving. Try to get to the bottom of the matter and work things out. Talk to him about how he is feeling, not just how you are feeling. So you two fight a lot, what's the fighting about and how can it improve. I tell you all this because you want to get back with him, however if I as in your shoes, I would never want to go back to a man who walked out on his family because we fight a lot. A relationship takes a lot of work, you can't just get going when the going gets tough.
