Is it normal for me not to want to break up?

I have been dating a guy for 5 years. He is not great with people and hasn't had a lot of friends. We have been living together for about 4 years.

About 18 months ago he started chatting with some ``furries``. They hooked him up with some furries in our hometown.

He became friends with a couple. I am not furry and am not really into it, but I tolerate it. A lot of the guys my boyfriend is now hanging out with are gay.

I noticed about a year ago that our sex life started to slow down. He wasn't into it, tired, etc. I thought it was regular life stuff.

On the computer we share I found that this one particular guy has been sending him some scary gay porn and beastiality videos too. I told him that this was not cool.

So, long story short. My boyfriend now tells me that he is gay. He wants to stay together but without a sexual relationship.

So, I guess I have a couple of questions:

1. Can a guy get peer pressured into being gay because he wants to fit in?

2. Why the hell don't I just break up with him and get him to move out. Part of the answer to that is that I really love our life together. We spend a lot of time together and enjoy lots of the same things. I know I sound really lame.

Could it just be a ``phase``?
