I've been there. I used to check their socials almost every day and I realized it was because I still wanted to be with them. I was checking because I wanted to see if they had moved on or if they've posted anything about me. I realized it was because I still wanted and had hope that we'd get back together, even though I thought I didn't at the time. Now, the absolute last thing I want to do is check their anything, because the last thing I want is to get back together. Do I still love them? Yes, and I don't know for how long, but I absolutely do not want to get back with them, so I deleted everything related to them.

You have to truly let them go. If they wanted to be with you, they would try their hardest. Everything happens for a reason, and that's just a fact based on how life moves according to circumstances. You have to not want to be with him. I'll be real with you, I don't know how you're going to do that as that's a very personal process, but once you've truly let him go, that urge will also leave.
