Love problems - what should I do?

Hey!

So I've been in a relationship with my boyfriend (gay) for three years now. It hasn't always been a dream of a relationship, but alltogether, I'm pretty happy with it.

Recently there have been some problems in my relationship and my boyfriend doesn't seem to really be interested about it.

So I have another friend who is also gay and he went through a life crisis during the last year and I kind of tried to help him whenever I could and now I think he kind of fell in love for me and I kind of have feelings for him.

But now I'm very unsure about what to do... Should I try to keep my relationship and minimize the connection with this friend or should I break up my relationship and try to somehow in some months or whatever come together with the one friend?

I know it's a stupid question, but it's perfectly serious.

Honest answers are appreciated a lot.
