Afraid of love?

The reason why I'm still staying single until now? (23th) even though i have male friends are because 1. I'm afraid that later after dating i found out that he is just toying with me and break my heart. 2. How if the guy that I like just wanted to take some advantage of me and not being true to me? 3. Some guys nowadays just lose respect of girls and treat them as nothing after they had their fun with them. I know I'm thinking pathetically here, but I want to be make sure of my relationship because when my heart is broken it is so heart to restore it. Few years ago, i really liked this guy and I thought this guy was feeling the same like I did because he gave me "what it turned out to be false signals" then I found out he was dating someone who was brainless whom he could control off and could be obedient to what he said. My heart was really broken into pieces, but crying the whole day was totally enough, I didn't want to waste my precious tears for that kind of guy. I was sure that he knows my feeling toward him still he kept me in the dark that he had a girl friend (what a jerk). Not because he was trying to protect me from broken-hearted but he wanted to use me to listen to all his problems, surely because his dummy girl friend couldn't understand him very well. Then when I think about it again if he's being like that shouldn't he just date with me? Rather than to choose that chick (ok her figure was nicer than me, but anything than that I can be compared to her), well that guy was a dummy ass jerk and I swore at that time never to let any guy to get me easily. Am I wrong if I have many qualifications for the candidate of my boy friend? I just want him to be: 1. Hard working and not living off to me 2. Kind and not temperamental 3. Non-smoker, not addicted to drugs and alcohol (I know many people ruin their "suppose to be good life" because of those things). 4. Respect me for my personality 5. Like me for who I am (weather I'm fat, thin, got hair problem, got lot of acne in my face). 6. Take good care of me, because I promise that I will take good care of him too. 7. Presented me with a loyal true LOVE. I wonder when and where can I get a guy who has such an unconditional love like that? God I hope that I will meet him soon and realized that he is the one for me. I don't believe love at 1st sight, how can u like someone when you don't know anything about him well enough. It could turn out that he is some psycho or may be an arrogant jerk, a playboy , etc.
