My boyfriend constantly flirts with my sister.

[Anonymous]

Ok, so I have a twin sister, and she's pretty, and funny, and smart. I love her to death, I mean;, she's my sister, we share everything. Right? WRONG! It's horrible, my boyfriend is constantly all over her and vice versa, they've even gone to the movies without me.

They both say it's no big deal and when I confront her she gets super mad, And when I tell him anything, it just starts a fight.

What do I do/

I'm not sure.. It doesn't seem like its the "nothing" that they say it is. If they flirt in front of you more, you should talk to your boyfriend again. If he gets defensive, just tell him that even though he may mean no harm, it still makes you feel sad. You should probably do the same with your sister.
