Yesterday while I was at work, my husband text me to tell me he's back on drugs. He has been for awhile. He was a pill head when I met him and got clean for me, we got married July of this year. Then yesterday he told me he's the unhappiest he's ever been, he wants to do drugs.. But he still wants me too. I told him he can't have both and that he had to choose. I didn't go home, I went to my parents house to stay, and I haven't heard from him since. Last year we went through a similar split up because he was unhappy, but he never told me drugs were involved then.  I can't tell you how bad my heart hurts and I want this all to be a nightmare. This is killing me. In my heart I love him with everything I have, but I feel he's choosing drugs over me. I don't want it to be over but I feel it has to be because he's choosing drugs over me. Saying I love this man would be an understatement. Some one please. Please tell me what to do. Please.
