Is this guy dangerous?

Sorry I tried to post this before and messed it up royally

This guy is dating my friend and I thought we were chill but they stopped talking to me about a year ago. I accepted the loss of the friendship and moved on but he's been sending me these messages and I feel so uneasy. Is this guy dangerous?
