Is my boyfriend lying about this ‘random girl’ or just being naive?

My boyfriend says a “weird girl” he has never met before near our apartment asked to use his phone. He helped her make two calls and even walked with her towards another building before stopping because she got “rude”.

Note: I have cameras facing the parking lot due to cars being broken into in the past.

What bothers me is how far he went to help her (their interaction last about 15-20 mins on and off). On camera, I can see he notices her, goes over to her after a few minutes, and they walk together. Then she gets close to him and even grabs his arm. If he truly didn’t know her, why was she so comfortable touching him, and why did he entertain it? I find it disrespectful, and honestly the camera footage makes it hard for me to fully believe his story.

I question if he liked the attention/interaction or was hoping for something to develop.
I also doubt his loyalty/honesty since he completely omitted the part (that she grabbed his arm). It also concerns me that he doesn’t set boundaries which can easily lead him into unwanted situations.

Lastly, due to how easily he walked with her to the front of another building and how touchy she was, it makes me wonder if she’s even a stranger at all.
