Annoyed at how lazy the bf is being about this

I'm 37 weeks and 5 days pregnant and I'm the only one working so my income is the only one purchasing everything for my baby. He doesn't try to get a job and we got evicted out our house I got us in because he started drama with the landlord over me. He is extremely insecure and we are sleeping on his brother couch and he accuses me of flirting because I spoke to his brother 1 time since we been here. And I tell him everything, and I put food in this house and make sure my kids have everything I can afford but he will spend all his change on cigarettes and weed but won't even save anything to by for the baby and it's been 9 months with no job on his part and he is 34 and won't even try!!! My parents won't let me go back because I thought he would change and their fed up with him. He is disrespectful to me about little thing and I'm getting annoyed because he doesn't care how I feel about the whole thing...sorry for rambling on but I'm freaking pissed right now!!!!!!
