Okay so I could be thinking this too deeply but I’m just going to explain what I’m confused on and how I’m questioning this....

So my mom is still friends with my ex who I was madly in love with for years, we broke up a year ago and he’s in a new relationship and has me blocked on everything, now my mom the other day posted a beautiful picture of me in a sleek black dress showing leg and he liked it, he also unblocked me on Facebook and Instagram. Now correct me if I’m wrong ladies and all opinions on this are open even feedback from you all but I have a feeling he’s creeping on me to see how I’m doing or he really misses me. We had a relationship for about 6 years that was long distance and a year together face to face and it was a very intense emotional relationship (a really good intense) what do you guys think ? Think he misses me and isn’t happy or is he just creeping on me....
