Sudden feelings for ex in the past, why?

I broke up with an ex boyfriend six years ago. About eight months ago, I started thinking of him and then realize I actually have feelings for him. Back when we dated I think I tried to protect my heart from him because I knew he wasn’t gonna be good for me. Im just confused as to why all the sudden I learn I have feelings for this person after all this time went by! Its been way too long! Makes me feel like I’m crazy and I’m not. I looked him up on social media and it looks like he definitely got a relationship going on. I acknowledge my feelings and just want to move on. I’m really not sure what this is that I’m going through.
