We have heaps of fun together, and physically (face, body, everything) she's my dream girl. I still can't believe she's mine. I was her first, and she is in love with me, and I with her. I wasn't a virgin when we met but she's the first girl I can say that I've loved. We've shared so much with each other, and have been dating for about 1.5 years. The problem is that she gets jealous very easily. She gets upset easily. And she can go from being crazy about me to thinking I can't do anything right/don't pay her enough attention at the drop of a hat. She really is my best friend and so so sexy but in the back of my mind I think that after the physical attraction inevitably wears off I might be left feeling resentful and irritated. Any advice from the married guys?
