Quick history...have been with DP for almost three years and his DD (who is 12) stays with us every weekend. Have had past issues with this due to space but have been much happier since we moved into a place with a nice second bedroom.
Have really chilled out a lot which DP has noticed. Get on really well with DSD as well and always have, we like the same TV programmes and laugh at the same sort of stuff which is good.
However, when having a chat with DP and DSD today, I mentioned that I had invited my parents to stay over on boxing day. This is because I usually go and stay with them for christmas but wanted to spend the actual day with DP this year.
DSD got annoyed at the thought of anyone staying in "her" bedroom. Now at the risk of sounding horrible, it isn't her room. She stays in it when she is here and leaves her stuff in there. It'll always be hers when she needs it of course and she knows that; but when she isn't here it's anyone's who requires the use of it.
She's not scheduled to be here on boxing day so I don't see the problem. I feel (not sure if this is rational but hear me out) that my family - and by default me - have been disrespected. After all, my family are just as important as DP and DSD and I pay half of all rent, bills etc.
Who is being unreasonable? More than happy to accept it's me if I am.
