Thanks to all guys for helpful comments.Well....I have talked about it with her several times. I have even threatened to leave her but she is OK for a few days and then the cycle starts all over again. Besides, it all statrted when she befriended a girl who is completely spoiled. Her friend has dated several guys and now shes with a black guy. As far as I acompanying her to parties is concerned, I work night shifts and hardly get any free time. Although I have assured her to accompany her whenever possible, she goes out almost everyday.In addition to that, She behaved so nicely for the last 1 yr as if she was the most homely wife imaginable.Now, I think she has started to believe that I will never leave her and hence takes me for granted. It has gotten so worse that I can hardly explain. besides, we have been living more like husband and wife rather than bf and gf. We have phone plans together and have invested in lots of things together.
