Boyfriend's Controlling Sister?

For some stupid unknown reason it sounds as tho she is jealous of you. Why she'd be who would guess. It's possible too his parents like you & talk about you when you're not there but don't say anything about her boyfriend. There has to be some reason why she acts so horrible towards you & does everything in her power to make life a living hell for the two of you. She sure is unhappy within herself to be such a miserable person. People who are happy within themselves, have self worth & self esteem do not do things of that nature, they do things to attempt to pull them down to their level. IF you could, I'd try to have a talk with her myself. Ask her what have you done against her to treat you in the manner she does & also why does she attempt to cause friction between her brother & yourself. Put her on the spot & get some answers directly from her. Say what you mean, mean what you say, & don't accept the unacceptable from her in any way. Tell her you just have to know the reason she acts the way she does twds. you all the time. Put the ball in her court & see how she returns it! I'd say it's coming from being jealous for some odd reason, but why?! See what you can find out from her...the best to you, Honey...:)
