Love triangle? Vent post.

So a couple of days ago I was on Instagram scrolling through my news feed & I saw a guy I follow post a picture of my ex (I gotta mention I was high key in love with this dude), but things didn't work out between us over dumb shit... We stopped talking & slowly kinda forgot each other. (I've always felt some type of way about ol' dude regardless tho). Anyway, the pic I saw was a literal prison pic & idk why I did, but I messaged the guy who posted it & asked if there was any way I can talk to him (I KNOW, THAT ISN'T THE RIGHT THING TO DO), but he told me about this app & I downloaded it & after a long debate, I finally put money in the thing & now we email each other & hearing from him was great honestly, but now I have a lot on my mind-- turns out I still really "care" for him. None of that would be a problem if I wasn't in a relationship now. He mentioned he would be out by next year, so I'm awaiting it, but I'm stuck. I have so much on my mind. Him & I went through a lot of crazy situations, I guess you can say we were kind of on some Bonnie & Clyde

stuff. We did whatever to whoever & didn't give a shit bc we had each other. People would say he was toxic for me, but I feel like they didn't know him like I did. I know, cliché. My s.o now & I are settled down & he's really looking forward to marriage & children, so yeah this is driving me crazy & making me somewhat depressed. I wish all of these feelings would just go away. I feel horrible doing this behind my s.o's back...
