Would you forgive your boyfriend for not helping you in a dangerous situation?

Hello, I need some input about a situation that I have.

I was going back to my apartment late after studying at my school’s library. All of the parking spots were full except for the ones in the visitor parking. I noticed that there was a guy by his car and he was just standing there. I felt scared and unsafe and since it was late, I didn’t want to get out of my car. At this time, my boyfriend was mad at me about something else. He was mad at me that I was at my guy friend’s apartment because I needed help with a school project and he thought the worst of me. This happened a few days ago. So, when I was in my car, I texted him that I need to call him for a bit so that I could feel safer walking to my apartment and he kinda jokes that that suspicious dude was another boyfriend of mine. I told him I was scared and he decides to joke about it. I ended up staying in my car and crying about it and had to call someone else for help.

This happened a couple months back and now he feels really really bad about it and he wants me to forgive him, but I don’t think I can after what he did.

Should I forgive my boyfriend over this?
