Was your daughter rebelling against you when she married him? It’s who he is. That is a change of mindset and heart you are looking for. Only Jesus can do that. And be careful- your daughter chose this one. She is getting something out of it that you either reflect or she hates about you. Maybe just try and be there for him. Women are manipulating- even,,, especially daughters KEK
She should have a nice dinner already habbining for when he’s home. He should be deciding on how he’s to support his family. If he ain’t abusing her- it’s none of your business. You sound like a good dad that wants to help. Encourage her to be more feminine and talk to him with a little lipstick on. If she can wrap you around her finger surly she can handle her husband.
You should also encourage them to stay together. Families are always better off with both parents. (Minus abuse, being a pussy boy doesn’t constitute abuse) Children NEEEEED their daddy’s.
You be the bast grandpa a guy can be. Take those kids hunting someday. Sounds like you been through some stuff with her mom- do not pass that on to the next generation. Use your head not your feelz
