Help me with this situation please.?

Am I in a bad situation? I'm 15, I've had one girlfriend in my life and at first I thought we were the absolute perfect couple, but she was a really shy one, took too long to really do anything. It was like a week before we even hugged, and like 3 months before we kissed. She said "since it was the first kiss for both of us, it needs to be special". Well I sort of see where she was coming from with this, but let's keep in mind, this is just a kiss, not ! We dated from the end of August to the middle of February, and despite how shy and timid she was, I loved her to death. But she apparently became unsure of that in the last month or two of our relationship and started saying she loved me even more, but spending much less time with me and favoring her friends more. She told me she loved me on the day she broke up with me, and she did it over the MSN. I haven't spoken to her since then. Anyway, I was devestated, and it took me months to get over her. Now I have, but I can't find anyone else. No one just seems to be a right fit for me. I'm not the guy who can have any girl he wants, either.... Only five girls have liked me in my whole life. Three decided to wait until they were done liking me to tell me they liked me. Then one is my ex girlfriend. The last one is this creepy chick who is really slutty and has mental issues. She's a year older than me, yet she's two years behind me in school. Most girls her age get pregnant on accident, but she's doing it on purpose! She WANTS a child, yet can't find a guy who will commit themselves to her. BIG SURPRISE! She's already had with 3 different guys, wanted it from me, I said no, she got pissed and now she won't talk to me. I'm not the kind of guy who just wants and nothing else. That's not me. In fact, I'm actually sort of afraid to do it. In the first place, the only girl who wants from me was probably swarming with STDs and is already PREGNANT. Thats definitely a total turn off if you ask me. Might as well save myself for the right girl and the right time right? Well there lies the problem, every girl I'm interested in has some problem preventing me from dating her. One moves away (she actually liked me back so ok theres 6 girls that liked me), the others dont like me back. Like I said before, I'm not one of those guys who just look for . I just want someone to genuinely care about me -- and apparently I just can't have that. Apparently I'm so damn unappealing that a couple of my friends suggest I go gay. I'm not doing that. XD I just wanna know... Is the situation I'm in common? Is there really anything I can do about it? Do I just keep waiting? I'm just bored as hell, and jealous of my friends who have had relationships that have lasted for YEARS and are still going strong. Makes me wonder why the hell my ex was so shy and appeared to be afraid of me. I have known her since before we knew how to talk. You'd think she would be comfortable around me, but I guess not. What should I do? :(
