<human>: Can you condense the text into three sentences or less?

I've been with him for almost a year, and our sex life was perfectly fine up until 2 weeks ago where he just didn't want it anymore. He doesn't touch me anymore, or initiate anything. I can't help but feel like it has something to do with me, and it makes me very paranoid and anxious also. I am huge on physical contact in a relationship. 

I know that this is most likely a phase, there is no way his sex drive is just going to be 0 for the rest of his life so normally I wouldn't even consider leaving. But I feel like he doesn't care about us and is just going along for the ride until the relationship basically ends itself somehow. We have other issues besides the sex drive, he kind of turned into a whole different person a couple weeks ago and he's colder/emotionless. I think he has emotionally 'checked out'. Whenever I mention that, he does not deny it. He told me that he can physically see me and he knows I am pretty but he still has 0 sex drive.

What should I do? Is there a way I can help him?
<bot>: Boyfriend has 0 sex drive and now I am questioning whether or not to stay because without his sex drive there is kind of nothing.
