Im 39 and my bfriend is 56. It works out pretty well except he hates my it when i change the xm radio to hair bands says that' s the
s*** he used to yell at his son to turn down lol. What matters is do you have the same spiritual beliefs, financial, marital goals etc.
Good luck! Ps. What also helps are his son and daughter are still younger than me. :-) that would be creepy if they weren't.
