Divorce Support Forums: New here, need advice

Well i have been married less then a year, and i am already getting a divorce.....sad, right??
Well my soon to be ex, left me when we were dating when i was pregnant with our son, was a total ass about it, did the typical guy thing, made it up that i was cheating on him, and he didnt know if it was his, typical immature punk thing to do...i raised our son by my self, but stupidly ended up giving him a second chance. We got married, i must be insane for that i know. He went through miltary school, and then moved us down here, first month down here was fine, and then the last three months he has been back at his old ways, being emotional abusive and negelacting his family and talking no resposbility of raising his son, i still fill like a single parent...he is gone 24/7 hanging out with his "boys" and when he is not he is putting me down, and making me fill like im nothing. Now he is filling for divorce saying im a horrible wife, and i treat him so badly, and i wonder where he gets all this....he is really selfless and only concered about hisself.....the twist, im a stay out home mom, just found out im pregnant again, and im 2 states away from my home state.....he is backing me into a corner, and i fill trapped, alone, confused and dont know what to do.....
