Need help for Muslim friend

Hi all,

I'm a gay guy who's been living with a Pakistani guy for the last year. We've been friends for the last 3 years. The problem is me and my friend became really close and about a year ago we had some sexual encounters and he basically went crazy afterwards. There was at a point where we were acting so much like a couple that I was 95% certain he was gay and 100% certain after we had hooked up.

Anyway rumours spread around his community that me and him were a couple and he basically went mad for almost a year. He said everything he did was for my sake because he was being a good friend to me but that he basically wanted to cool off for a bit. So a year has passed and in that time he has had deep depressions, lost his temper a lot, had many fights with me and has basically been miserable. We used to go out every weekend but he basically stopped going out, stopped having a social life and plays xbox all the time. Things have gotten a lot better in the last few months. Our friendship has gone back to being very strong and he seems less depressed than he was when he was at his worst.

My problem is that now his life just seems to have stopped. It's almost like he lives the same week on repeat every week, and never wants to enjoy himself. I stayed with him though all the hard times while he was severely depressed because i was worried for his health and safety. Now that he is not so depressed I feel like I should move on and let him grow in the direction he wants. I guess as his friend I want to continue to help him and be there for him. I am almost certain he is struggling with his sexuality but off course i can never be 100% certain because he doesn't like talking about any of his feelings or issues. I know that he still only watches straight porn, yet he lives with a gay guy and he loves me so much he has basically lost his mind when I said I would move out somewhere else.

I guess I would like to know if anyone has been in similar situations? I'd like to know from someone who has been through what he has been going through how hard it is? and how long does it take to accept? Is it normal to just watch straight porn and be in denial or could it be that he is just in fact straight? I basically would like to hear the perspective of someone going through similar so I know what is the best thing i can do for him. I feel like he is wasting his life at the moment and so I should just move out so he has the freedom to do whatever he wants. I also know that he would be devastated if i moved out as well and i don't want to make things worse for him. I don't know what to tell him because he doesn't like talking about any of this stuff and when we've been fighting in the past the things he says makes me feel like he is living in an alternative reality and complete denial about the issues. I've heard that when people are going through such things it is best to leave them to sort it out themselves but i feel like as his friend i should try something to help him move forward. Any advice or insights into his perspective would be helpful.
