Dating Older men

I am 23 years old and I have a hard time communicating with guys my age and i always feel like they are a bit immature, i have dated a guy who is 10 years older and it still didn’t work. Now I like this guy who is 17 years older than me ( pls don’t judge) and I feel really embarrassed by the fact that I am in to him. When we hang out he is even the crazier and fun one. I have decided not to date him and to keep him as a friend but I miss him. I just wanna know if there are people out there who are happily married to someone wayyyy older.
