Single and Ready to Mingle

So I just very recently just became single the girl I was in a way dating was actually talking to someone else but I wasn't always the best boyfriend so I kind of deserved it. I wouldn't say that I was a cheater or anything I'm just very flirtatious and I have a lot of girls who are friends and I guess my former girlfriend took it in the wrong way. If only she knew that she was the only one I cared about then maybe we would still be together but as of right now were not even talking to each other. Deep down inside thought it hurts me that she doesn't even have the decency to tell me that she doesn't want to talk to me anymore that she is seeing or talking to someone else. I had to find out through a Facebook and the fact that she was so sloppy about keeping that other person a secret makes me even more angry but hey maybe things just we not meant to be. As I talking to my father about the situation he told me that I am to young to even really be tied down to one person. Now my dad wasn't telling me to go out and hook up with everyone but he was just saying that I need to enjoy my self and enjoy being young and that I don't have to get married any time soon. He also told me as well that if I search for someone that,that person wont be a good and that I just need to wait and let that person find me.
