My boyfriends best friend likes him a lot, she's always over at out house and asking to come over when ever she's not, its gotten to the point where I barely get time alone with him. Except at night, she constantly is messaging me, or him asking if she can come over. At one point she was rubbing her leg on his, he instantly moved away from her, and came and sat by me, he does not flirt back with her, or invite her over ever. If she ever comes over and my boyfriend isn't here, she leaves right away. I know he's not cheating on me with her but, her flirting is getting annoying, to the point I want to never let her over, but I know her and my boyfriend are to good of friends, and I would never ask him to stop being friends, I'm not jealous, I just feel its disrespectful.
