Well I do see a couple problems here that could be contributing factors.
One being you don't open up. Now I'm not saying you have to go and spill all of your secrets to every guy you meet. But if you do start getting close to a guy then try and share a few details every once in awhile. It shows that you trust them and want them to be close to you. Put yourself in a guy's shoes. Wouldn't you want them to feel like they can share with you?
Another problem I see is you said you never text them first. If no guys are talking to you, then take initiative and talk to them first! There's absolutely nothing wrong with it and everyone loves when somebody puts in effort to have a conversation. Not only does it show that you actually want to talk to them, it gives you more opportunities to talk to guys.
I don't think there's anything wrong with you either that is keeping you from getting into a good relationship. Sometimes these things just take times and remember the attraction has to come from both ends meaning you also need to have feelings. So you should start by looking for a guy you could see yourself with. Then work towards becoming friends with them, and then if they don't take things further then its time to tell them how you feel.
Just take it one step at a time and don't stress yourself out over being single. As you said, you're doing just fine.
Also, there isn't really anything wrong with being picky but remember that if you judge people before you get to know them you might miss out on dating a really great guy. So just make sure to keep an open mind.
