My boyfriend and his ex wife are in the process of selling the family home which they both still live in.
She has a long term boyfriend.
He and I met 18 mths after they split up.
I have no concerns about them wanting to be together or anything like that.
When he and I went back to his this weekend to look after the children, it turns out she had helped herself to sleeping in his bed while he was at mine. She slept there with their daughter, and left her things there.
My boyfriend was clearly surprised but said things like, she is taking the piss, and, no point getting stressed about this, it will soon be over. I said very little except queried her boundaries, to which he said, she has none. I doubt very much that he has said anything to his ex about it.
However I feel quite strange about this. I sleep in this bed on the weekends my boyfriend has his kids. When I first stayed there, my boyfriend reassured me saying that his room had been his room alone for well over a year. I felt like some sort of mistress seeing her stuff there this past weekend (and I was nothing to do with their divorce- we didn't even know each other existed).
I am wondering if I am overreacting? I haven't said anything to my boyfriend but am wondering if I don't sleep there and wait til he has his own place. At one level this seems unfair as my boyfriend didn't know she was going to do this, but, honestly, I find it so icky.
Advice welcomed re the musical beds.
Thank you.
