Search Results: having sex and breaking up

This is about my boyfriend and best friend. I've been together with my boyfriend for about 3 months now and best friends with a girl for about 6 years. Recently I've noticed that they have been talking more with each other than with me. He is also acting the same way he acted around me when we just started to figure out we liked eachother. They sit next to eachother in every class, always playing around with each other, talks about sexual things together (they even talked about them breaking the bed while having sex with eachother!) and when my bf and I are both sad she will go to him even though she's only known him since the start of the year. by the way I've known him longer.

She has told me she likes him a tiny but but says she would never date him. I've asked him and he says he wouldn't date her but I don't believe them. I tried to break up with him last week but I got back together with him because he was so sad (I didn't do it just out of guilt I'm in love with him).

I'm also really upset because I feel like she cares more about him and tells more stuff to him than to me. Another confusing thing is that he tells her he loves me, that I'm beautiful and how he wants to marry me when we are older! I'm really upset because I know they like eachother but I don't know how much!!
