I told one of my ex girlfriends that I'm transgendered because she moved across the country and that made me more comfortable, and I thought that of all the people I'd ever met that she'd be the most understanding.  And she was, at first.  But then she says things about how my notions of gender are outdated, and displacement stuff, but she's only trying to be helpful.  But just now I was really opening up to her about my gender problems, my work problems, and my development problems AND about how I'm trying to work on them to make them better.  She just totally dumped a bunch of her problems on me, which is fine, except I suspected (and then she confirmed it by telling me) that it was to show me that "my biggest problem is no problem at all."  She's been being more and more progressively a bitch lately, and she's really starting to hurt me really bad like every single time I talk to her.  And she started the damned conversation in the first place.... I have that feeling in the pit of my stomach that rumbles of tears, but I haven't been able to cry for a while.  Why is she so mean to me?

I dunno.  The only reason we broke up is because she moved away....

No, she moved away because her family lives half way across the country.  It's a thing I knew about from a couple days into the relationship.  I don't know what it is about her that makes her want to cheapen my situation.  Not to mention I'm still upset about her moving, even if I did know about it in advance.... but that's not what I'm upset about right now.
