Pregnant & feeling lonely. help?

my husband and I have been together for almost 3 years . we got pregnant with a baby girl and lost her in Nov 07 at 19 weeks. Now we're pregnant again (24 weeks) with a baby boy . He doesn't really go out except to the park to play basketball and to work and almost everyday he's in the kitchen with all his loser games doing the dumb $hit guys consider to be fun(video games ,etc.). Saturday night he went to his best friends party. After saying to me late that night "im only gonna sleep here for a few hours cause I'm drunk", he just got home at 6 something PM monday evening. I was feeling kinda funny so I called his friends phone a few times to make sure he was really with him (he was). I'm going to Florida in a few days to stay with my mom n dad for a while and I put how excited I am in an away msg on AIM. he got mad because he says I'm acting like I wanna leave forever. after he gets home, he goes right into the kitchen to hang out with more of his friends, and right now as I type, he's putting on bball cloth
