When people become constant reminders of your flaws

Everytime i see someone, I feel like a bit of an asshole.. I know that I was cold and unclear in the way i removed her from my life.. I think I owed her some explanations, and I admit that communicating about the things that upset me is not something that I know how to do well.. I just saw her leaving alone, and I felt sad, because we used to keep each other company, but when I didn't want her company anymore, I just started pretending that I don't even see her around. I don't think this is bad, everyone is allowed to decide whom they want to spend time with... but i just think the way i accomplished that was the problem.

On the other hand, yep, with time she seemed a bit selfish and sometimes even condescending.. maybe not all the time, but i don't want to be around that.
