My girlfriend ghosted me 6 months ago and I've changed what I consider a lot in those last 180 days.

I dropped 45 pounds, put on a bit of muscle (for the first time in my life), got a couple tattoos and a nice new beard I'm rocking now.

Anyways, I'm by no means a 10 now or anything, but we recently crossed paths, talked for a few minutes, and now today she texted me saying she thinks about me sometimes and how maybe we should try to be friends.

What is happening and what should I do?
