DP and I live together in DPs house. It's a really happy home.
One of DPs relatives wants to stay here while we're on holiday. The relative is very problematic, I don't like being around them. Instinctively it's a no from me. The thought of them in my home when I'm not there makes me feel really uncomfortable.
DP is less bothered, because it's their relative, but completely understands how I feel and says they will tell the relative they can't stay even though that may cause other difficulties.
Problem solved?
On the other hand, family is important and I don't want to cause problems for DP. I don't want to be an arsehole. I think I would be able to handle my difficult feelings and deal with the situation so the relative can stay.
Should I?
