I find my DGC tiring so I’m with you on that OP!
I think, as others have said, these children have had a lot to cope with and their DGD has given stability when they were/are going through changing times. It isn’t every weekend and I hope your DH will see your side of things if you try to spend at least some time with him and the DGC, and then organise lovely together time when they aren’t there. Please talk to him, he does sound a very genuine man.
Good luck.
