Search Results: ex is getting married

My (kind of) ex published her first book a few months ago. I read it, and I really enjoyed it. I left a great review for it on Amazon.

Here's the thing, this girl and I did NOT end on good terms. She lied to me about having a Fiancé (it was an arranged marriage deal), and then blocked me on all social media after he and I found out about each other. We weren't even dating but the shit got weird.

In the time since we went our separate ways, a LOT of life has happened. Personal tragedies, careers getting started, etc., and I'm pretty sure that they aren't getting married anymore. I don't know the specifics of their situation (and nor is it my business), and I would think an arranged marriage would have happened by now.

This happened... wow... 4 years ago.

I've definitely moved on from the whole situation, and I wanted to reach out to her through her public email. I'm definitely ready to talk with her again, if she'll allow it.

Should I reach out, or just let the past in the past?

My ex and I broke up 3 years ago, and it was an incredibly difficult break up according to my friends.
Anyway, last year I suffered a severe head injury and suffered massive memory loss, seizures, and massive headaches for months. The memory loss still remains. I don't remember practically anything before the injury.
But I ran into my ex, now married, and I didn't recognize her. But she bitched me out for something I did during the break up. But I had no clue what she was talking about. She slowly understood that I didn't know her or the situation and my friend explained my injuries.
She cried and asked if I remembered her at all, and I didn't. She seemed familiar, but I didn't remember anything. She was upset that I wouldn't remember the good times we had, and my friend ushered me away because she was getting too upset.
My friend says I'm fortunate to not remember her. But should I feel bad for how she felt or anything?
