I discovered my boyfriend of several years has a relationship with another woman. He has been acting differently with me for months and I could see him slipping into some kind of depression. He told me in the beginning he was bi polar but was not medicated and that he worked out everyday and that helped him control his emotions. Well his working out has also created a monster. He is on anabolic steroids, taking Ambien at night to sleep on top of Advil PM and now is drinking. He developed a relationship with a younger woman at the gym he uses and to what extent i am not sure. He says he loves me and had I not caught them (she uploaded a video of him working out on her Youtube page) I would have never known. Here is my problem, he is not taking any responsibility. He says we were not getting along and that he does love me and he has now told her he cannot do this and is distancing himself from her, BUT when I try and discuss it he turns it around to be my fault and then gets very verbally abusive and says he is sick of both of us. I want to think he is having a manic episode because he is always talking about how he looks and how much weight he did at the gym and taking up with complete strangers and having long conversations and seems to be more sexually aggressive. He is acting like he is the MAN and if something was wrong it is someone elses fault. His close guy friend was critical of him and he went off and told him he no longer wanted to be friends. He dog (which is like his child) is also been diagnosed with cancer and not doing well with the chemo.

I am not trying to excuse what he has done to me OR find a reason to take him back. I am seeing a totally different man than what I fell in love with. Is he truly sick now OR just a cheating asshole. Sorry for the long thread....
