OP,
Great wisdom and observations above.
Stop doing ANYTHING for him.
I mean ANYTHING.
Then have a long hard look at your relationship.
Someone using his home as a hotel and out more than he is in, is a man who has opted out of his marriage and family life.
He certainly is not a man who is in love with you any longer.
I don't mean to hurt you, but this is the reality.
He likes you, but you are not essential to his happiness.
You need to be looking at what you want from your life and making your plans, but being realistic doing it.
My friends younger sister was in a similar situation as you a couple of years ago, but it was golf that was his priority.
He would have thought he was a happily married man with 4 children, good career and a marvellous swing🙄.
Life was good until it got back to him that his wife had had the house valued and he was asked were they moving to.
By this time she was long done and had her ducks in a row.
Two years on, they are still together but he plays 10% of what he did and HE is still working on her staying together.
My friend doesn't believe they will survive, as her sister is largely ambivalent about him now, but is going to see the children all into secondary school.
Too much bad feeling.
Protect yourself.
