Sorry, this may be a little long! Basically the background is that I have this cousin who I used to get along with fine when we were younger. She moved to the UK once she was married a few years back and I was pretty hospitable to her, despite having a baby and a full time job and living a ways away. I used to be her go-to person when her husband was away. Anyway, she showed up uninvited to my place this one time when I had my mother-in-law staying, and was pretty much demanding throughout. She refused to eat the food I made, and made me cook separately for her, sat on the computer all day long, ignored my husband and mom-in-law... we all made a huge effort for her, but she persisted in being a complete brat! Finally she went back and had the cheek to post on FB about how she would kill herself than live in the country like some people... it really hurt me!
To cut a long story short, I was polite to her even after all this as I did not want to cause a rift in the family (her dad's the unofficial 'head' of the family!!) Recently I found out that she had taken me off her facebook account. I thought it was a mistake, and added her again, but got the message soon enough. She's still friends with my mum and sister. On Christmas, I found that she had sent a e-greeting to the whole family, including my mum and sister but not to me... she knows for a fact I would find this out. I was unbearably hurt at this! DH thinks I should cut all ties with her and that she's acting like a spoilt child, but I still feel hurt and used. AIBU?
