SO is VERY Distant. :(

So, I found out a month ago that I was pregnant with our rainbow baby. I was so excited I couldn't wait for him to get home so I sent him a picture of the pregnancy test. Ever since I told him I was pregnant, he has been terrible to me. Always yelling/screaming/cussing at me in front of our 2 year old son. It's starting to get to me really bad. I have tried talking to him about it. But he tells me not to feel that way or tells me he isn't being mean. Well last Wednesday night we got in to a huge fight and I cried so hard I started throwing up. I ended up losing my pregnancy (again) on Thursday night. I am at a complete loss. I need him right now and he is being the worst person to be around. I went back to the hospital on Saturday for them to confirm the miscarriage, and while I was gone he moved his friend in to our house without consulting me or anything. When he took me to the hospital on Thursday night, he went out and sat in the car while I was in the ER being told I was going to lose our baby. I have so much resentment towards him over this. I can't help but feel like if he would have been supportive and understanding instead of yelling at me for anything and everything I did, then the baby would still be with us. I am to the point of wanting to leave because I feel like the only reason he wants me around is for a live in babysitter. He only wants to have sex when he wants it, I pay most of our bills, and I'm the one who takes care of our little boy. I'm not sure what to do at this point. :(
