Is it normal to get a handjob from an ex without talking about it?

BACKGROUND: I dated a girl in high school for about 2 months, between junior and senior year. She was a virgin who seemed really innocent and fell madly for me, she would say 'I love you' on a regular basis. I said it back to avoid awkwardness. I was also her first ever boyfriend. I realized after a while that I was not attracted to her and I only went out with her because I had my heart broken by another girl, so I liked the attention and the idea of it. One date at the movie theaters, she started rubbing my knee, moving towards my thigh, and eventually started groping me, hard. This surprised me because we had never talked about anything sexual. I broke up with her because I did not want to be the first to have sex with someone that loved me and I did not love back.

Many years and several relationships later and she started hitting me up because I had recently broken up with someone of two years. It was winter and she convinced me to hang out with her. Hanging out eventually lead to making out. However, due to getting drunk with her dad and both of us embarrassing ourselves, we stopped talking. I went back out with my ex and broke up again exactly a year later.
Whenever I'm not with someone, I find myself talking to her.

Now here's the thing, whenever I hang out with her in private (usually going to a movie, like a drive in theater), she starts touching me, even though. Note that she is still a virgin and has not ever dated anyone else still. She has reached into my pants and I went under her clothes to see her reaction. Yet, we have never had sex or even more, we still have never talked about. Every single conversation we have ever had has never been sexual. I tried bringing it up and she avoids the subject. All we talk about is normal, 'how was your day' or 'what are you doing?'

In conclusion, we are not going out and touch each other sexually. Yet our conversations are as nonsexual as a normal conversation between common friends.
