Bf abusing pain killers

Hi. I’ve been with my man for a year and a half, I’m currently 32 weeks pregnant with his child. I also have a 2 year old.

We moved into his parents house until we could get into an apartment. We’ve been there for 4 months, and ever since we got there he’s been taking Hydros.

I’ve caught him 2-3 other times. This time, he openly admitted to me. I suspected he was taking them but shrugged it off. I don’t know what to do.

He has troubles keeping a job and he says it helps him and makes him happier at work. They’re not even his either. They’re his parents and I’ve tried talking to them about it but they just don’t care.

I tried talking to him about seeing a psychiatrist but he won’t make an appointment. I’m losing all hope. I love this man.
