Should I leave him?

[questiongirl]

I have been with my bf for two years now but I can't seem to shake this feeling that he likes my sister a little too much. There is this flirty face that he always made at me and one night at the restaurant I saw him making it at her. Am I being riduculous? He acts a little different when she's around too. Like he'll drive faster, turn up the music really loud...as if he's showing off? He treats me better than anyone I've ever dated, and I know he truly loves me. He tells me everyday that he loves me, has always been there for me and tells me all the time that all he wants is to make me happy. He has matured a lot and grown up a lot since we started dating and I know that it is because of me and also because I've made him realize he needed it. Am I being stupid or are these flags something I should pay attention to?

DO watch them, it all depends if you can trust your sister and/or your partner. I am a man who is going out with the middle one of 3 sisters and my gf has been wary sometimes. For me being an only child it's very strange to see another 2 women that look different but act the same way and say the same things as my missus. It all depends how far all of you let flirting etc go. I've lost count of the number of times my gf's sister has mentioned a "sister sandwich" when we are all together. Gotta go now I....err....have to wash my hair!

Ugh! I hate this one - even if you ask him he will deny he's doing it - but u know he is. He obviously hasn't matured that much. Just be sure u can trust your sister, as then u know if he does try anything then a) she'll tell you and b) nothing will happen! If you can't trust her, take not of her behaviour around him and if it is like he is being towards her, either dump him before it's too late or keep then well away from each other.

You know sometimes you are just attracted to someone and you can't help it? And you end up being really goofy around them, and can't be relaxed? I get this sometimes, and I have no control over it! It doesn't mean I want to have sex with that person!! It just means there is an attraction- an appreciation, that is chemical, and you can't help it. It has nothing to do with real life or love. I wouldn't worry about it. So long as your sister doesn't fancy him, nothing will ever happen!
