I want sex, but not from boyfriend.

We've been together for about 7 years and think he's a great guy, but those feelings of intimacy have faded for reasons I'm not sure of. I know it doesn't make sense to be feeling this way, but I do. I'm just not sexually attracted to him anymore and don't feel like having sex with him.

It started just about 2 years ago when he tried to initiate sex as usual by laying in bed with me and rubbing my legs and stomach. But my body was reacting as if some creep had just walked into my apartment and started touching me. It was strange. But I just told him I'm not in the mood that night.

I thought maybe it was just a weird feeling that would pass, but it hasn't. I'm starting to realize I'm not attracted to him anymore and maybe I've been keeping that feeling suppressed for a while now.

And to be clear, it's not that my sex drive has started to fade. I see other more attractive men in my day to day life who do stir up a lot of sexual energy inside me. I just don't feel that way towards my boyfriend anymore.

He has been complaining about the lack of sex and out of guilt I gave it to him a few times, but I'm not into it at all. And to be honest I ACTUALLY DO feel guilty for no longer being attracted to him. He has done a lot for me! And he was there for me during some very difficult times in my life. But as of right now he more feels like a helpful roommate who guilt trips me into sex rather than a partner.

I'm writing this because I'm not sure what to do, and hoping others here can relate. Should we break it off? Should we seek couples counseling? Is there a way to overcome no longer having romantic feelings towards your partner?
