There is too much anxiety and questions around personal safety with this person. I agree with the other posters -- IF he was attacked, why would he continue to use the same APP to meet people? And he IS rushing things by asking to meet your parents. Promising not to hurt you raises a flag for me too.

I wouldn't meet him with this many questions and with this amount of uncertainty. It all seems off and likely that he lied.
