You know...I've often wondered that myself, and I'll be frankly honest here; I am not entirely sure. I didn't HATE her...but...I resented her. I resented her because she knew I had a very weak self-esteem and that whatever confidence I brought to bear was often little more than bluster and facade, and she thought she could use that to take advantage of me.
I guess it was spite. Sacrificing her for myself, because she had been intending to do the same to me first. She intended to walk all over me. She DID walk all over me....and I needed something to reassure myself I wasn't a doormat.
So I found something to reassure myself of that. I found someone else. But why didn't I just plain break up with her? Ego. Always the fragile male ego.
