Drug use and gay porn (Not a joke)

I have been with the same guy for over a year now and we have lived together for the past 7 months. I recently installed a key logger on my computer after I suspected he was doing things he shouldn't be and deleting the history. I found out he has been watching gay porn online. I asked him about it at one point, saying he had left it in the history, and he claimed he just watched it to "see what it was like" but that he "wasn't into it". He has watched it almost every day since.

He also is a 8 months clean opiate addict. I am sure he is still clean of opiates, but he is smoking pot and doing something called "Whip-it's" almost every day now. He finally just got a job after being on unemployment for the past couple of months, but it is at a shop that sells pipes and such.

I am a college senior with a 3.4 GPA and my whole life ahead of me. I am about to graduate this spring and planning on moving across country closer to family.

I really do love him, he is the only guy I have ever felt this close to. When we are good, we are really good. I'm just afraid I'm sticking with him because I am too comfortable. He is no longer what I want in a man, but part of me hopes he will go back to being the responsible man he once was.
