Why not involve them? I know, stupid question. Maybe you need to sit down and explain that we all need "me" time, and that getting away for a couple of hours will make it so you're not so "bitchy"
. Know what I mean? My girlfriend and I used to go round and round with this same issue. I was practicing long before I met her. After awhile I just flat out said either go with me and see why I like it so much, or have a Coke and a smile, and shut the **** up! Now she loves it to the point of where if I'm not paying attention, she'll throw me around the house like a rag doll. Use the reverse psychology on them.
