Sorry to be blunt (no pun intended) Get a new boyfriend or be single for a while….if he is doing drugs now he will probably still do them if you are pregnant and still once you have the baby…..at this point he has no intention of being "a family man" if you really want to get married and have a family one day then I would suggest looking for a man who is not caught up in drugs…people used to tell me that marijuana was the gateway for all other drugs…I used to tell myself "no way, I can smoke pot and not try anything else…" well within a year or so I had done two other drugs and after like 8 years I had done everything but heroin…I have been clean of any and all drugs for about 3 1/2 years now and I have no intentions of EVER doing them again….get away from him before he starts doing everything else….Meg
