My boyfriend and I have been together over two years. He has relapsed several times. At first I didn't recognize the signs when he uses because I never was around it before. But after awhile I knew when he used. When I confronted him about it he would lie. And finally weeks later he would come clean. He is always making excuses for using and trying to make it my fault. He has been in and out of rehab but nothing works. I love him but don't know if I can do this any more.
