I met a HB8 in class recently and we've went running a few times together and have done some homework together. This weekend however I planned to escalate and invited her over for a movie. While watching the movie she kept her distance and wouldn't come close to me on my bed. I eventually got to touch her a little with some middle school tickle-fight bullshit, but she eventually said she had to leave to meet friends. I was at least expecting to get a goodbye kiss after walking her to her car, but all i got was a christian-side-hug. I went back inside pissed that nothing happened where my roommate commented that I was probably in the friend-zone. After some thought I reasoned that I would rather not be in the friend zone. I decided that I would invite her back over by telling her that I forgot to give her something. Then when she came over and I opened the door I would nut up and kiss her. Some of my friends had their doubts to say the least, but it worked to perfection. I opened the door and she said "this better be worth..." but before she could complete her sentence I had her back against the wall and we were making out. I invited her inside and she ended up staying the night. I didn't seal the deal because it is that time of the month but I think that its pretty clear that I will soon. I definitely wouldn't have even had the confidence to approach her in class if it hadn't been for this subreddit and a lot of reading. Thanks guys.

TL;DR: Didn't regretted not kissing a girl the first time she came over, invited her back over the same night and made out with her like a boss.
