Problems...

Awhile ago while depressed, I ended up cheating on my boyfriend and between us we had fixed stuff up as much as possible. While he will never trust me with said friend.... we are fine.
He admitted to cheating on me... so, I don't know we just work thats all...

Said friend (we will call him D) had kept trying to get me to come over again and constantly wants to see me... he even keeps telling me he loves me even after telling him I do not feel the same and I am with my boyfriend. This contributes to my boyfriend's discomfort even more....

However, before this all happened- my bestfriend (we will call her A) was dating D. But this was a long time ago and A has a boyfriend now...

This stresses me and my boyfriend out because she constantly makes this problem about her when the two of us want to forget it ever happened and move on. She goes to D's house and talks about what happened and he construes what happened in ways that make me look like its my fault only...

so in return, A goes to my boyfriend and tells him.... and he gets <staff edit> upset <staff edit> at her all the time...

We just want this thing ended and I don't know what to do to make it be the end of it. Like I said, me and boyfriend ended it in our minds but those two keep bringing it up constantly and creating more drama....

I don't know what to do, i already cut off D, and the worst part is that he doesn't even know or seem to care. I thought that D cared about me all these years and he has helped me alot.... my bf thinks it's just cos he wanted me...
