Why am I having bad luck?

Hey people,

I was wondering if anybody could offer some insight as to why I am having bad luck dating... Please allow me to explain.

So far, since going off to college, on that one app that shall remain unnamed, I have been offered hookups and stuff like that on a daily basis. Hell, I even got offered money. And I'm not talking like just a few dollars.

Of course I didn't accept. I'm not at a point financially where I need to do so, yet... And I hope I don't. But it's worth noting I don't judge anybody for doing what they need to do.

ANYWAY.

First person I met, cute, we shared a lot of interests. we chatted for a good while. Then, he says he doesn't want a relationship because he's still hung up on a crush on a straight guy, and doesn't see that as right to me. I say, okay we can be friends. We meet, chat, do homework together. I wished him a happy birthday that weekend, which was a few days before mine. He says thanks. Nothing else. Not one word. Not a happy birthday, not a how are you doing.

Next person, cute, we met up, at this point I felt starved for any affection. Like just in general affection, hugs, cuddling, whatever.
My judgment lapsed somewhat, and he gave me hickeys. 3. I had to go buy makeup and embarrass myself checking out when a girl I've seen around campus who was standing next to me looking at nail polish offers to help. Her boyfriend standing beside her. They both help me pick out a concealer that matches my skin tone better, and a color wheel to counter the purple from the bruises.

Now, the most recent guy.
Cute, muscular, former military, served active duty in the army, 23. We chatted for a while, we went on a date that actually went really well. He bought me Chipotle and we talked for a while. He walked me back to my dorm and we hugged goodbye.
Now you see. This is where I made my mistake. Since the date went well I was maybe getting my hopes up a bit.
Today we went on a walk around campus, we talked. Well, he did most of the talking. Literally. About topics I couldn't really contribute to the conversation on. The moments when the topic WAS somewhere I could engage, the topic would change before I could get a word in. Then we sat on a bench outside my residence hall and talked for a while. Again he did the majority of the talking Only at this point, I was able to talk more for some reason.
But then he does something, after a minute, he comments on how some girl was dressed as she walked by. Saying she was dressed like a prostitute ready to stand on a corner. "I mean it's college and you can dress how you want but..."
Now I didn't see her. Even if I did I wouldn't care, you do you. But I'm not exactly sure how I feel about that. For this guy, if there is a 3rd date, it's outcome will determine whether or not I am open to being in a romantic relationship, or just friends.

Can somebody please enlighten me as to why i am having bad luck? Like seriously.
I don't get it, I've been told I have a warm personality and I am easy to talk to.
And I hate to sound conceited, I really do, because I hate acknowledging it.. but I am cute, at least I've been told that. I'm short, have a very slim build, a physique that as far as I'm aware, many guys find attractive.

Can somebody please enlighten me as to why I am having bad luck? Like, relationship wise, I want something between long term/very serious and friends with benefits. I want a boyfriend, that maybe, perhaps in time, could grow.
But if I am going to be honest, I am also lonely and crave some kind of attention, that's putting it a little lightly. Hence why my judgement and mental blocks kinda lapsed with guy #2. But Since that did happen, i feel I can hold myself together, it served as a reality check. It's not like I'm so eager for attention that I'm willing at any time. I just feel like. I don't know, it's difficult to describe. I feel lonely, I guess.
