Struggling To Talk/know What To Say

My boyfriend/8 month old daughters dad is snorting heroin. I met him 2 years ago and we instantly were in love the first day grant it we were both fresh out of 6 year relationships. He has 2 boys from his previous relationship. She is my first child. We grew up different and hung around different type of people, I've never even tried drugs and quite honestly they terrify me to even be around someone who uses them even recreationally. He suddenly started using pills the month before our daughter was born & kicked it and was sober until she was about 1 month, then it was back to pills since then it has never stopped all together maybe a week or so here and there sober but that's the longest I can recall. I tried before to cut him off for the protection of my daughter because I don't want her raised around his addiction. I told my family & they encouraged me to focus on her and forget about him, she's what is important which I completely agree. I can't seem to get over worrying about his health/safety and feelings. In the past 2 months he has started snorting heroin because "pills just don't work anymore" 2 weeks ago I told him he can never come back to my house again and his daughter doesn't need to see him in the place he's at in his life right now. Again the feelings of worry have engulfed my life along with lacking the courage to not let him stop by to see her for a few minutes here and there. I need some serious advice, I'm leaning away from telling my family because they haven't liked him since the first time he put us in this position with pills alone. I feel like I have no one to talk to and don't know how I should deal with the way that I feel. Any advice or help is much appreciated!!
Hi Danielle, I think your doing what's best for you and the baby already. Chances are maybe he's been doing this longer than you think? You should confide in your parents and get them to help you during this time. But I would do what your doing keep him gone and don't let him in the house. I don't know how it works with custody of a child when the mother and father are together, do you? If not then you need to see a lawyer and find out your rights to your daughter. Last thing you want is him visiting and taking her. Drugs like heroin are a hard thing to beat. But it all depends on how long he's been using. I don't believe what he's telling you but I could be wrong. Their great liars when their trying to get you to trust them again. I hope more people will advise you but please go talk to a lawyer about your rights and tell them he's doing drugs. Be strong for your little girl and don't let yourself worry about your boyfriend. She needs you more than he needs you. If he was looking out for you guys he wouldn't have got himself into drugs. You don't need this kind of life. Move on!! Good luck to you Danielle. I hope more answer your post. Mary.
