Cherry, I am going to differ slightly from Sexy Sara.
Since your WH has confided in you that he may be having mental ( did he say he is depressed?), I thought you could perhaps do him a favour and make him an appointment. But then that's it. Ecerything else is up to him.
Good job on biting back your tongue when you realised the discrepancy in his reality and yours.
I don't know if we should treat your H as having sort of a MLC? It seems that we're more inclined to treat MLC spouses more kindly? But I am not a vet, not well- versed in MLC.
You can call me Dory/ Grl.
As a wise fish once sang,"Just keep swimming!"
It's no use to go back to yesterday because I was a different person then.
