What would you do?

I came online this morning to a couple of DMs from a man I used to know through ep. I used to be on ep when I was 13/14 years old! It was a time when I didn’t really have a handle on my emotions and this person acted like he cared. He gave me a lot of support, we talked a lot and eventually moved over to using Skype. That is where he groomed and abused me - not that I realised that’s what it was at the time. His messages say that he has always looked for me returning to the site, he’s missed me and is a different person now. Part of me thinks I should just block and move on, but there is part of me that wants to know why he did that to me.

Any helpful suggestions?

(I’m not going to name and shame, it’s not for me to do that. He’s probably going to read this so I may get some answers without needing to ask)
