Boyfriend lying, relapsed on heroin.

Long story short he was released from prison a year ago. Has been clean for 2 years. Relapsed after miscarriage in September. He said he wasn't gonna do it anymore. Since then he has lost 4 jobs, stolen money from my purse and stole a drill set from his brother and pawned it. We have had to revive him 3 times from od. Im working 2 jobs, 8 weeks pregnant and he does nothing but seek out ways to get dope then lies about being high like im stupid. I have completely detached from him and have not one ounce of trust for him. As soon as i get approved for this house Im leaving and hes not coming with me. Am I wrong? I refuse to raise kids around a junkie. I can't even keep money in my own purse.
