Is my boyfriend in the wrong?

Not a while ago, I was out for the night to get some coffe with my friend.

My boyfriend was home, playing his video games as usual. And as I was heading home, I noticed someone following me and got really scared so I texted my boyfriend that I think I'm being followed, to which he just replied that I am probably imagining, and he continued playing the game and wasn't online for 20 minutes.

Needless to say, I was being followed as the man started running towards me and I ran into the shop to escape. I was later angry at my boyfriend, he just brushed off the fact I was terrified, and when I said that I wasn't imagining as he was clearly trying to do something to me , my boyfriend didn't even ask what happened.

He didn't care. I told him that, I just told you I had a traumatic event and you don't even ask me what happened, to which he replied "well I was going to ask you but I thought you are probably angry at me so I didn't " .

Is this normal behaviour? To me it isn't. I'm his girlfriend, and to my concern that I am being followed he just told me I am imagining and disappeared offline to go play his game. Am I overreacting?
