Recently I went on a road trip with a friend of mine. Almost the first thing she felt the need to talk to me about is my girlfriend, who is transsexual and beginning the journey of transition. She showed a surprising amount of hostility and personal animosity towards her, attacking her appearance, saying she "doesn't try hard enough" and generally holding her to standards she would never hold a cis woman to. For example, because my gf doesn't like makeup and feels comfortable enough to sometimes wear jeans and a tshirt (a fitted girl's tshirt, mind you) on the weekends when we visit that somehow she's a "failed" transsexual. I wear jeans and t shirts most of the time and am generally more "masculine" than she is, and I don't hear anyone attacking my gender presentation.
I explained some of the difficulties of transition, including the fact that we are extremely poor and don't have much money for clothes. Most of my gf's wardrobe has been trolled from thrift shops and closeout sales, or sewn by me to fit her. It isn't huge, but it is growing, and yes sometimes she does wear boy clothes because she *has nothing else to wear* but if you look when she does she always has a bit of feminine flair (colorful tights under ripped jeans, cute jewelry and hairstyles). She is beginning to finally find her own style and gain confidence, but she's not going to transform into a fashionista overnight. My "friend" kept interrupting me and saying she should just try harder and expressing a complete lack of sympathy.
I haven't told my gf about this conversation because I know it would hurt her. She considers this woman her friend, and we all see each other on a regular basis. Because of this and a couple of other (unrelated) conversations since I don't really want to hang out with/talk to her anymore, but her husband is one of my gf's few friends in the area, and we go over there most weekends for tabletop roleplays. It's one of my gf's few opportunities to get out of the apartment for something other than classes (we live in a horribly boring area) and really important to her.
We're only in the area until I get my associates degree this December, when we'll be off to greener pastures. (Part of the reason she decided to start transitioning here; it's a temporary pitstop, and allows her to get past some of the more awkward stages and develop some self-confidence with relatively little at stake). Should I just grit my teeth and talk to my "friend" as little as possible until we move on? I don't want to make a big scene and cause drama, but I just don't feel comfortable around her anymore. She disagrees with my gf at every opportunity and harshly and I don't know how to deal with the situation
