Little update...
I ignored her for almost three weeks and minded my own business. This wasn't easy considering my friends so far insist on keeping her as a friend. Wednesday she got ahold of me and we talked for a bit. She was angry that I pushed her out of my life but said she understood, that she still cared a lot about me and wanted to be there for me. I told her that if she had wanted to be supportive, then she would have been supportive instead of making my life a living hell in a time of need.
She asked if I had preferred being lied to for a month, I said that's not something I have an answer to, but that I never had the chance to sort out the problems the relationship might have had while my mother was sick. She re-iterated that there had been problems before my the whole ordeal with my mom; namely that I got along really really well with my mom to the point of seeming a bit clingy. Hell, I only saw her twice a year for a few days. So, her feelings just "disappeared".
She insisted it was not because I had weak moments during my mom's illness. I believe she believes it because else she hopefully wouldn't be able to look in the mirror in the morning.
She was very touchy-feely, and I made the mistake of falling for it. I got her hot (I know her weak spots, obviously) but then she blocked and said she didn't want to do things that would hurt me even more. Ouch.
I can deal with her being gone - what I can't deal with is my friends still hanging out with her. They spend their time with me, but insist she is still a friend. Meanwhile I'm losing sleep not over her, but over whether tomorrow I'll have to deal with hearing about her, seeing her or being told my friends hung out with her or seeing them Skype her.
I have the feeling I'm being too nice - I told my friends it's not helping, the less I see and hear of her the better, yet it doesn't seem to help. I'm considering exploding at them to get my point across.
