Idk why but I just really want to add my exes on social media..

I’m married now with a kid on the way.. but for some reason I keep wanting to add my exes on Instagram and Facebook again. Idk why, maybe deep down I want to rub my happiness in their faces? Or maybe I’m genuinely curious how they are? Idk.. but idk what to do. I want to add them but I feel like that’s a bad decision. And idk how to get my mind off it:/ help ... also I didn’t know where to put this sooo...
