My sister was divorced several years ago and is sole parent to my niece who's almost 16. Her ex lives abroad and sees his DD rarely. I used to get on really well with DN and spent quite a lot of time with her until she reached the age of around 13, at which point she started to become obnoxious. I ignored the snide remarks and lack of consideration or gratitude for as long as I could, but last year things reached a head.
She and a friend of hers came to stay with me for 4 nights, as they have a couple of times a year for some years. I live in London and when she stays I do things with them that they wouldn't be able to do where they live. Last year we went down the Thames to Hampton Court on a boat, we shopped at Camden Market and Spitalfields and Hoxton, we went to Tate Modern and the Globe theatre, we saw a couple of shows and a couple of films. I pay for everything, obviously. DN's friend was lovely. DN was a complete nightmare. Didn't want to go out and do anything but was angling to go clubbing and angry with me for saying no. She was 14! Didn't want to go anywhere I suggested, couldn't suggest anything she'd like to do. One day we had a quiet day locally, because she was so adamant about not going out, and she complained we didn't do anything. I tried talking to her to find out what was going on, but she told me to eff off and then had a furious rant at me. She was really trying to be hurtful. I soaked it up and tried to comfort her friend, who found the situation difficult, but it really spoiled the last couple of days of their visit and she had another major outburst in the car when I took them home.
Last Christmas I bought her something that I'm sure she'd said she wanted. Something that cost £300. I was there when she opened it, with my DM and DS and other family members around. DN opened her present, pulled a face and then threw it at me and said 'You're as shit at buying presents as everything else' and walked out and slammed the door on us. My DM was shocked. My DS went after DN and told her off and there was a big row that ruined the day. DN hasn't spoken to me or contacted me since then. I've messaged her occasionally and she's just ignored me.
My DS knows what DN is like, but is still anticipating that this August I'll have her and the friend to stay as usual. As the time approaches I feel less and less like doing it. Their visits cost me over £1k, which I don't begrudge. But I'm not going to spend that sort of money and also soak up the abuse.
I've contacted my DS to say I'm not sure I want to continue the tradition. My DS says she has to face this kind of behaviour every day and it's just part of dealing with teens. She's actually accused me of being unreasonable for not carrying on as usual. AIBU?
