When the invites first when out for my shower, she immediately RSVPd "no" to the hostesses. (For what it's worth, she lives two blocks away from the house where the shower was, could have walked there in 5 minutes.) I never addressed it with her since I'm not the one she RSVPd too, and plus she does things like this all the time just to get attention (so that when she does show up all attention is on her for actually attending).
The day before the shower, she sent me a long email that had one sentence about me ("Have fun tomorrow) then about 7 paragraphs on how even though one bridesmaid (a family member) has "begged" her to come, she isn't because she doesn't want to be out of place (she is mad that she isn't the one throwing it, even though that's bad etiquette, so she said she feels embarrassed that she's been cut out and would feel like an imposter) She said "maybe some day" she'll "make it up to me." She also wrote that in order to attend the wedding, she will require two of my aunts to stay with her at all times so she doesn't have to talk to anyone. Even though these aunts are travelling over 1000 miles to attend and probably want to enjoy the wedding, not play babysitter. I didn't respond because I frankly didn't know how to.
The day after the shower, yesterday, she sent me a long email again late at night (right before I went to bed.) The first sentence asking if I got good presents, then another round of long paragraphs about how she was psychologically paralyzed in bed on Saturday and couldn't get out of bed at all and felt so sick. I was going to respond this morning, but before I got the chance she just sent me another random email about her thoughts on the NFL draft.
I am really having a hard time either not responding at all since I am upset that she didn't care to show up since it wasn't all about her and I don't think her behavior merits a response, or sending a snarky response along the lines of "if you really cared about it, you would have shown up." But, since she is probably going to be at the wedding, I am trying to keep the peace and be on my best behavior. It bothers me that she expects me to comfort her when I'm the one she should be apologizing to.
So, I am going to respond to her, I just needed to vent a bit before writing back. I'm going to be the bigger person and tell her the shower was nice and that I hope she feels better, and leave it at that.
Then, after the wedding, I'm going to talk to her one on one and let her know how much her behavior has been a distraction and stressor, and that if she wants me in her life she can treat me like a person, not an emotional punching bag.
