Confused

So I broke up with my ex boyfriend about 5 or 6 months ago, and he got a new girl etc. He blocked me from social media and whatever I went through the break up stuff alone very depressed got myself together and I realized it wasn't worth it to cry over 4 inches, anyways I notice that he unblocked me from ig cuz he been watching my stories once in a while, but he stills dating this girl like dude are you unhappy or curios? Any thoughts on that?
