+1 on that.
When I was married I also had a band. My wife liked the band. We had a weekly rehearsal and some gigs – nothing too crazy. As it went along, she started to do become, I think, jealous of the band. She’d call me during the rehearsals. Things would “come up” and I’d have to miss a session. We’re no longer married. I still have music. Sadly, It was an irreconcilable difference. Music was not why the only reason we parted but it was part of the parting.
I always hope there can be reconciliation in any relationship and working for it is worth it but there’s limits to everything.
Write her a song about it and if you both cry maybe things will get better.
I sincerely wish you good luck in working it out.
