Ah, again it's a pressure kind of thing. The way you find someone will be the same way they find someone; luck (or karma or whatever you want to assign it to). Just using the shotgun method of "I'll date everything I can find" doesn't necessarily lead to a strong relationship any more than being careful and trying specifically to find the right person does.

For example, I've had 3 girlfriends my whole life. The third one I married and I've been married for 13 years now. My wife dated almost constantly, but didn't want to get married until she found the right person. Now she's the only one of her friends that hasn't been divorced.

So what I'm saying is focus on your relationships, focus on quality over quantity. I think this last relationship hit you pretty hard and you might consider talking with a therapist to help you through this rough patch. But believe me, when you understand that you have to work at relationships and put effort into them, you'll find that love you want.
