Im a younger guy (15) and I’ve been dating this girl for a while, she’s incredibly important to me, it’s going great. She’s clearly into me too. Our dates are light hearted, flirty, touchy etc however in our more recent date I had an opportunity which I lost, We were touchy, slapped each other’s butts and held hands but later on in the date we decided to go cinema. While we were waiting for the movie we watched memes and our faces were really close like a cm or two away from each other, she kept on licking her lips, looking at mine, we kept on getting closer and closer till… nothing happened, I couldn’t make the move and kiss her. I was always on the verge of kissing her but when I actually tried I just couldn’t something stopped me. During the movie she had her arms crossed and her body facing away from me. I got so nervous that I had great trouble to make a move and grab her hand.
I want a relationship out of this but how do I stop this from happening ever again? Also I’ve noticed that she became a lot more dominant since the last dates, is this some kind of test? Why would this be? How do I prevent this?
