Why am I so relationship challenged?! haha?

Okay, so I am 22 years old, and I have never had an official "boyfriend." I always just talk to guys for a short period of time, go on dates, and mess around sometimes when I want to. I really want to fall in love someday, and I definitely want a family. I honestly don't care about having a boyfriend at all right now, and I absolutely love being single because I feel so free and independent and able to do what I want whenever I want. I tend to really like guys that I know are assholes and just want to hook up. The thing is, I am so physically attracted to those guys, and I know that they are not the relationship type. For example, I hooked up with two guys in the past 3 months, and I honestly couldn't stop thinking about one of them. I got so upset if he ignores me when I see him out, because I want him to pay attention to me. However, if he would want a relationship and be the one to come on to me and ask me out on dates and stuff, I honestly don't know if that would push me away or not. When I like a guy and we flirt, maybe hook up, but nothing too serious, that's when I get like completely infatuated. But I get instantly turned off if they text me too much or be all sweet by asking me on dates. whyyyyy do I do this?! I desperately want to fall in love, but I will admit that I am afraid because I am so used to being single and loving my life (since it has become a habit), that I don't know how my life would be with another person in it. Also, I am a very indecisive and picky person, and I feel like I would change my mind a lot about who I want to be with. What is my problem? I definitely need to fix this by my mid twenties because I don't want to be single forever.
