When I first met my best friend I tried to get with her and I ended up in th friend zone. We've been best friends since and I've kept my true feelings hidden. I know this is bad to say but I find her more attractive than my girlfriend. If this was a crush on a random girl it would be fine but I see this girl every day so I think my new gf probably should know.

And a bit of context I've kind of built up this image of my best friend's beauty in my head like you would a celebrity. I know it's not healthy to do that to a girl but I couldn't help it. One time she wasn't wearing a bra around me and I saw her nipple and it was like seeing the holy grail for me.  I know that's kind of random but i think it's important for understanding how i feel about this girl's looks as well as her personality.

Lately my best friend has been hanging out at my apartment while I work because of her new roommate. Which sounds fine but she likes to take her bra off when she relaxes and usually wears tight shirts so you can see a good amount. Normally this wouldn't be a big deal but now that I'm in a relationship I don't know if I should be in this situation so much.

My girlfriend is fine with it because she just thinks we're best of friends but if she knew how I really felt she probably wouldn't want me spending this much time with her.

TL;DR! I'm kind of in love with my best friend and don't know if I should bring it up to a girl I'm starting to date.
