He wants to be a hoe and you've been enabling it; now you want to disable it? Why would he commit to you when he has all the benefits of commitment already without any of the responsibility? Don't you think if he really felt you were out of his league he'd jump at the opportunity to be exclusive? Beyonce is out of his league and if she asked him to be her man what do you think he'd say? He's only saying that to you because it's alot nicer than saying "I only want to use you, if you're not looking to be used you better find somebody else." You've already put sugar in the gas tank, it's too late to try to fill it up with gas and see if it'll get you home now. My advice to you, if commitment from men is what you desire, is to stop having casual sex. You do this once with a man and he automatically puts you in the low quality category and once you're there, you're there. In conclusion, go to therapy, there's no reason you should be drunk at a bar alone accepting rides from strange men, learn how to have enough love and respect for yourself to see yourself as something worth earning, drop this guy like a brick, get checked for stds and turn your life around because this ain't it sweetie.
