I find my brothers long term live in girlfriend hard to handle. She's 10 years younger than me, very extroverted and seems to take control of everything, when I basically want to be left alone.
There's been something that is really irritating me though. When she sends out cards or gifts to family members, she signs them with my and my DDs name on as well as hers and my brothers. This has been irritating me for a while. I'm currently visiting my parents and it was my Dads bday last week. There was a bday card from her, with my name and my DDs name on too. Obviously I sent a card to my Dad from me and my DD, and I've visited this weekend with a present. Last night I said that I was really irritated by the way SIL does this and my mother just replied that that was how she was, and I should just be less irritated. That made it worse, and basically I want to send SIL a sharp email telling her this is not normal or acceptable and she should stop. (There's no point talking to her - she doesn't listen.) Just to be clear, I do not have any sort of reputation for ignoring/forgetting bdays and other events in my family!
AIBU to get so irritated by this? Should I send that email? It's been going on for some time, and I know it will continue if and until I make things very clear to her.
