I am a complete beginner at this stuff,had two long term relationships,4 years each,which means my game is 0. I've never approached a girl in person or online until a month ago,my two girlfriends approached me. I've installed tinder,still havent approached anyone in person but I figured it's a place to start. So I went out with some girls,I fucked up all the meet ups until 3 nights ago. I went out with this girl and we really connected.I initiated kino and we got really close,my hands were all over her the whole night and hers as well. Problem is,for some reason I did not kiss her,even though it was obvious she wanted to and that created a wierd vibe because of all the touching,holding hands,hugging,etc but not kissing. Last couple of days we talked a bit but she is very distant compared to how she was before meeting me,and says she does not have the time right now to see me again. Should I let her go and move on? Was my mistake so big that she lost interest?

If anything,for other beginners out there,learn from my mistake.Never keep kino going for too long without going for the kiss,it eventually makes things wierd.
