Older men

I’m 26 I just meet this guy he is 41, I’ve always been into older guys but never dated one so much older then me. We get along great and he seems like a sweet heart, we have hung out twice and talk and talk often. He has two children one in college and one in high school whom he has with his ex wife ( the kids live with the ex wife). I guess my question is would his kids/ family accept him for talking to someone much younger. He says he wants us to have a relationship I’m just not into dating a person if it means having his children disapprove or be upset at there father. I believe the children come first.
