first of all, face & height how you'd rate yourself?
secondly, by 30 i assume you're earning good, can compensate the first point just in case
thirdly, are you boring that made girls unable to continue chatting? or you'd say you got no prob in maintaining conversation?

lastly, if all else dont work out, it's fine being single, at least you're free to do whatever you want, if want to satisfy your needs just do it outside using your money, think it positively as you're going to get to try many pretty ones (albeit at a price) instead of fixing to only 1, and perhaps saved yourself from "wife sex" or no sex, it's common married people gradually moved to no sex, usually caused by 1 of the party, and caused another party frustration, end up eating outside too.

single or attached, each has pros & cons and no clear cut advantages, pick your poison.
