It sounds to me like your husband loves his son and is being supportive of him. Is he really babying him by going to his band gigs to support him and cheer him on?
Is he coddling him when he makes sure that his taxes are done right or that his resume was right so he could get or keep his job?
He spends time with him to play pool for a couple of hours a week.
Sounds to me like he loves his son and wants to see him succeed. Is that really so bad?
You only touched on a few things that were addressed- going to his gigs, helping secure employment is one thing.
I also agreed that it is great he spends time shooting pool together- they need to have that man time/bonding time. There should never be conflict over that. They need to have their time together and burn off steam as well as have fun!
HOWEVER: Did your dad help you find a girlfriend? That is not typical or normal behavior.
Sounds to me he does not make any effort to do anything on his own rather complain to get dad to do it for him. He has it all figured out that he can manipulate his dad into doing what he needs.
If you love your children- you teach them to be independent and self motivated, not co dependent and need Daddy to take care of business. he is 28 and is old enough to be on his own.
Sometimes you got to push your babies out of the nest and MAKE THEM FLY- I know it's a hard thing to do when it is your child, but sometimes you got to let go for the greater good.
