Most Helpful Guy
When I was in his age range I dated a couple of older women.
I've always been a decent guy, the only times I was ever called a player I'm pretty sure were in irony. Maturity wasn't my strong suit (still isn't) though, and even with the best of intentions I had problems dating older women who had their sh*t together when I was in my mid twenties.
The reason was that I had the expectation that an older woman deserved a lot more assurance of relationship success than I could provide. Just didn't know where I'd be a year from then, or how I'd feel about being in a relationship with an older woman at that point, either. Why lead her on? At the same time, why blow her off? The sex is way better, the conversations are too.
Men are not at the peak of emotional intelligence at his age, despite the nearly perfect confidence they possess.
The advice I'd give is to let it slide a while longer, but give yourself a deadline. He's got to mull things over and there's still competition in his mind from video games or new cars or beer pong, what have you. Trust him if you want to about other women. This advice works whether he's a player or not.
Give yourself three to four weeks before re-examining things. Then give him the thumbs up, or thumbs down, to his face. Say, "I let things go and gave you your space and now you have/haven't calmed your wobbly-kneed-colt self down and we can/can't go forward in a mature relationship from here."
He's got to miss you a bit to see if he's ready to leave a little more adolescence behind and take on the mantle of manhood a little more.
