Pregnant, jobless and don't know what to do...

Ok…I have been with my boyfriend for 8 months now. I’m 31, he’s 41. Currently, I don’t have a job and neither does he. We both just recently lost out jobs. We also live with 3 other guys in the house who none of them work but one guy because he’s military. My boyfriend has friends come in and out the house everyday just getting high, watching movies with all of us and speaking his spanish and b.s’s all night long and to top it off I’m pregnant! I told him not to come inside me and he did it anyhow! Its the second time! Earlier in our relationship he got me pregant, but we I had an abortion for obvious reasons. Then, I asked him why did he do that when I told him it wouldn’t be a good idea to have a baby right now due to both of our situations. The answer he gave was, “I felt like being stupid” I’m like???WTF!??? I guess sometimes he feels like a nut, sometimes he don’t…I guess in this case he felt like a nut…god I feel like a used abused, call girl/ho…I’m so stressed and depressed over this. We never use protection. He pulls out but not this time because he just felt like being “stupid” Now, there is a possibility I might be pregnant, again…This is not right… HELP! Oh, and he wants a baby BAD! He said, he’s all for it! But, I don’t feel ready, still? :-( I just feel like so bad because the baby. And I’m really trying to get my life in order before a baby can pop up in the picture. I just don’t know anymore…I guess to him it’s a game..
