JaneQ, thank you!
Hubby and I have just contacted our therapist for an emergency appointment. Hopefully we can get one next week. If not, it probably won't be until the end of June.
We have had quite a heated discussion this afternoon. It still didn't become an argument but it was as close as we ever come.
We just both feel like it isn't something we can compromise on and we can't see a path through it. I don't like upsetting him and he doesn't like upsetting me so we are both feeling a bit crap about it all.
