I have a dilemma with my 22 year old daughter. She lives at home with us and has a boyfriend. She really wants her boyfriend to come into our house to spend time with her. As far as I understand that's against current covid rules, and we'd be breaking the law to allow it. She's really upset with me for saying no and says it's impacting negatively on her mental health. I feel conflicted. It seems likely that on 17th May some restrictions will be lifted and that we will, hopefully, be able to welcome him into our home. She says that if I continue to say no until then she will feel long term resentment towards me. It's a recurring discussion/argument that's making for a bad atmosphere in the house. I'd really appreciate people's thoughts to help me through this. Am I being reasonable?
