I have two teenage children who live with me. My partner has one teenage son who lives a few hours away from him. My partner and I don’t live together for a number of different reasons but we generally have a really close relationship and see each other a lot. My partner isn’t able to have his son stay over with him at the place he rents and needs me to have him stay at my house when he visits for weekends once a month and for five separate week-long stays during school holidays. I’ve never been completely happy with this as I’ve always felt it encroaches on my time with my own children but I let it happen for a while until recently it got to the point that I became resentful of feeling obliged to do it as it was changing the dynamic of the house during the times I cherish most (e.g. Christmas and summer holidays etc when things are generally a bit slower-paced and I can enjoy time with the children without having to run around to clubs etc so much). Things came to a head this Christmas when I said I couldn’t do it any more and I want my house back to myself for me and my own children to enjoy some downtime during the holidays without having to feel self-conscious about having another teenage boy in the house. It has caused a rift between me and my partner as he feels I’m not supporting him or being a team player. AIBU?
