I had alarm bells ringing in my head when I read your question!
I know everyone gets mad and makes mistakes, and maybe you could talk to him about it and explain how you feel? It is possible it may never happen again.
But - and it’s a big but...you said you were hurt and now you’re scared.
That says to me that you don’t feel completely safe with this guy - that’s not a good place to be.
Scared is the same as being frightened and panicky and intimidated - all the things that are the opposite of the way a guy should make you feel - like loved and wanted and cared for and secure.
It’s never easy to walk away, especially if you have deeper feeling for someone - but it could be the best thing to do.
Stay safe and happy. X
