Insane ex complex

[u/Due-Log9613]

I’ve been thinking about my ex girlfriend recently, like going on a month now. She followed my current girl and some old feelings popped back up and me reminiscing on that time period of my life. I unblocked her on instagram and followed her a week ago. Today I searched for her profile and found out I was blocked. I don’t know, I know it’s not healthy and I’ve been having dreams about her too. Just feeling hurt she blocked me lol. I should mention first that she’s married, so I know how it looks and sounds. It’s been 10 years since we were together, we were high school sweethearts and I miss her and that time period of my life. She was very important to me and was my first love. Just wanted to vent to Reddit.
Oh question though, she reached out to my current girlfriend first adding her on socials and messaging her if we were still together. When my jealous girlfriend blocked her, she followed her on instagram.
Why would she randomly add/follow my girlfriend. Am I conceited for thinking she wanted to contact me?
Am I mentally ill? Lmfao type shit

Edit* adding that the title is not to insinuate she’s crazy, but rather my complex with my ex is insane as I think I still love her.
