In my social circle their is this Mexican girl who I like hanging out with. The language barrier is difficult at times. I think she wants something serious but she is into me. I noticed that she will take my phone and post a boomerang of herself on my Instagram story. She also will ask me to take a picture of us together and then tag her for the story. She only gives neutral responses to physicality and maybe a positive like leaning in.

Last night we were hanging out in a group of friends and she posted on my Instagram story. We all went to go watch a movie and I sat on her bed with her while she was on her phone to watch the movie. Later she layed on her stomach and said to give her a massage. While massaging her I started stretching her legs and the massaged her calf's and then started to move up to her thigh and she said that's high enough so I went back to her back. She asked if I was checking her out and I say "yeah I'm not gay". After a little I layed next to her on my stomach and she gave a look like what are you doing but a smirk that showed she liked it. But she got up and layed on the other bed and continued playing on her phone. When I was going home she didn't come out to unlock the gate and shut it once I left.

What would be the way to handle this situation?
