DH is Christian and he and his family are quite religious- goes to church weekly etc. I’m not Christian and I don’t attend church or do anything religious, I’m pretty much an atheist. We hosted DH’s parents and siblings and partners today. His parents wanted to do prayers before Christmas lunch. I told DH I’m not happy about having to do it but just let them get on with it whilst I sat there. In the evening, they wanted to do more. I’d had enough and I left the room without saying anything and let them crack on with it. Half way through the DC (toddlers) realised I wasn’t there and left the room to see where I was so they missed some of it. DH was so angry with me that I didn’t partake as it was a “whole family unit” thing and it disrespected his whole family? Apparently I ruined the day and now he’s sleeping in the spare room. AIBU that’s it my house and if I don’t want to do religious prayers that I sit out and go into another room ?
