Husband moved out after 4 mo of marriage ignoring me?

My husband moved out, willingly he wasn't thrown out or asked to leave, althrough i did tell him in the heat of our argument that if he didn't want to be in the house then leave we argued about money and him lying about paying bills. In which he promised to get his act together. I strongly believe in marriage seeming that I come from a back ground of two parents who were married over 30 years until my dad's ping away 6 years ago. We have only been married 4 months, when he decided to leave so i thought I would give him a couple of days to cool off and then try to reconcile well he ignores my calls tell his boss to tell me he isn't at work, turns his phone off in the evenings so that I cant get in touch with him when he gets off of work he turns his phone off and wont return any of my calls or emails. Then told my brother that he doesn't want to be married anymore. I'm really hurt because I love him and he knows it but could careless I've been knowing this man for 3 1/2 years he is 49 i'm 38 so were not talking kids althrough with him its questionable. I really wanted to save the marriage but i cant do it by myself should I just let it go. When we were dating he up and left me for 2 months with no reason what so ever and come back I have a child from other relationship that have really learn to love him. But I'm not sure what else to do since he's not responding to me no kind of way. By the way when he left he took his clothes only he still has furniture in my house from when he moved in after we were married . Should I just wait for him to contact him and then ignore him, walk away from this my heart just cant take this kind of abuse very sadden. not sure what to do.
