She thinks I'm wrapped around her finger. So I know what's going on...but I don't know what to do PLEASE HELP?

Me and this girl have been off and on together...but never have actually been together. It seems like when ever we start having fun and getting really close she pushes me away then we come back to each other and its not just a friend thing either. this has happened at least 4 times with each time we have been progressively gotten a little closer. I recently told her how I felt about her. That I had feelings for her and cared about her but if I'm some guy she's just gonna string along then that's effed up and she said no to that and hasn't really pushed me away yet but I don't know if she will. And this isn't just me talking to her...we've been out on dates a few times (like 3)i text her.she texts me and she's told me that she wants to do all these things with me in the future

i asked her if she had feelings for me and she said she did. But I feel like she only wants to hangout at her convenience and that she thinks I'm wrapped around her finger. Were are not together and I know she doesn't want a commitment right now...but she still thinks its cool to text this other guy a whole lot and hangout with him..and for me to tell her how I feel about her and for her to think this is cool...really pisses me off. I don't know how to explain this to her without looking like a needy insecure douche. I'm crazy about her and she knows it...i know I can't force her into a relationship but HOW CAN I SHOW HER THAT SHES LUCKY TO BE WITH ME. We have a crazy amount in common and I feel such a great connection with her...What should I do? thank you for any help
