Why do guys lose interest?

[the ice man]

If you were not frustrated would you find of interest?

I know what would make me lose interest if my girlfriend constantly nagged me and bitched at me. if she constantly whined about how I'm not constantly giving her my full undivided attention. If she started getting complacent about her looks. Also if she were always PMS'ing I would lose interest. If she always had a negative attitude and saying negative things I would lose interest too and eventually I'd dump her and find some one who isn't a grouchy old bitch. This is just my personal opinion I'm not saying you're any of those things
