I’m not sure if you’re actually dating Kevin, or if he’s just a man you’ve met who you’re possibly interested in. I wouldn’t worry about the age difference too much, but I would be very aware that sometimes he doesn’t call you, as you say.
That alone wouldn’t be of such concern, but the fact that he hangs out with women, some of whom he has slept with, and that you say he’s a party guy, and you’re not, makes me think that this may be more of a rebound relationship for you rather than a match that could go the distance. 😐
He’s also at a big advantage because you live in a community where women outnumber men. 😕
My advice to you would be to keep things light with him, and don’t commit your heart to a man you’ve only known and/or dated for a week or two. Try to get out and meet other men because you’ll not only increase your chances of meeting someone more compatible, but you won’t be putting all your eggs in one basket with Kevin!
It’s too soon to say if this could turn into a serious problem, but there do seem to be some incompatibilities between the two of you from the start that may not lead to commitment or marriage.
Hope this helps! 🙂
