A kiss on the forehead would’ve been acceptable?

So I met this girl online and we matched. We talked for about a week and some change and bonded over healthcare. She (22) has aspirations to be a nurse and is in the beginning stages of pre nursing and I (23) am already an icu nurse. She said that me being in healthcare caught her eye but as she got to know me through talking she found me interesting. We decided to go out on a date to the arcade and then have dinner. With my past relationships and not seeing red flags when I should I wasn’t focused on making a move and instead kept my hands to myself and didn’t do anything but analyze how she is. Overall she had a good time and she drove over an hour to come to my area in Florida (she’s in Miami with crazy traffic and I’m from Fort Lauderdale). She gave me a hug and headed off for home. After the date she was questioning me as to why I played it cool and that I shouldn’t do that the next time. But she seemed stoic and I didn’t want to go for anything the first time meeting her to scare her off. She also is interested in my past relationships and says that at some point we are going to have to talk about it. She also said that I don’t have to be as nice or that a kiss on the forehead or something would’ve been great. Would this harm my chances.
