Need a little help with life

I'm not too sure who to turn too or what to do! Hoping any of you lovely ladies can give a helping word. From the start of last year after coming out of an abusive relationship i decided I didn't want another relationship for a lonnnggg time. Decided on a friends with benefits with a person that wasn't very understanding..which lasted till July just gone so it was on and off for a while! He's recently started talking to someone else which is great! I'm extremely happy for him. (Found out from Facebook as he's not the type to say anything) still feeling like a relationship wasn't for me I kept guys as friends however they do flirt. I agree to meet up with them in a friends way to catch up but I'm always afraid they'll think of it as more... I even have a guy best friend that I've had to continually tell him it's not going to happen.. but now I've found this guy who's absolutely amazing! Works hard!! Is extremely sweet with dealing with my emotions and disabilities. And i actually want to be with him! It's been so long since I've felt like that! But now I feel like I can't be with him even if I wanted to it he asked because of all the guys wanting more and thinking they can get more when I assume they are friends. I don't want to put myself in a firing range as they say. I'm scared the guys will ruin it for me and I'll go straight back to the girl who doesn't want a relationship. Could anyone help with this dilemma? I really just want to be happy and don't know where I've gone wrong these guys are probably going to give me trouble if I get with him but do I stay away? I don't know
