1st, you have to get over the fact that you were cheated on. Yes, its rough. But it happens. I've had a lot of bad things happen to me through relationships. But i get over it.
And as far as all these girls 'not wanting to be with you', do you know this because you're running around asking every girl out? That may be one reason no one wants to be with you.
Or are you just assuming?
The point in finding a girlfriend is to lead to marriage. If you want to be married, you'll have to take the risk of being hurt. If you don't care about being married, then there is no reason to date. But it sounds to me like you're a bit angry and bitter, between being cheated on and not being able to snag any woman you want. Dating takes time. Some people have it easy, others have to try harder.
But, as itore stated, ideally singleness is the way to go, if you can handle it. Even Paul stated this in the bible.
