My husband is a very nice person. (He’s also bloody annoying a lot of the time, and I’m sure I am too.) About 18 months ago he took up the guitar as a hobby. I’m glad he has a hobby but he plays it about 4 hours a day all round the house, not very well but bearable. Worse, he sings along and he has a terrible out of tune singing voice. He also has ADHD and Rejection Sensitivity Dysphoria so gets really upset at any suggestion that he can’t sing as he really likes music. It’s torture. I am quite musical, can sing well and have recently taken up a new instrument but I practise for an hour a day in a room with a closed door. He is driving me potty. How do I deal with this without hurting his feelings, I’m worried one day I’m going to snap and it will lead to a huge row and he’ll be really hurt.
