When we were in contact briefly, my ex said he would check up on me via my social media account. I used to wonder if he did this. I know I do from time to time because I want to know he is OK. Not sure what his motivation for looking at me is.
Goddess Erikka said that he would be checking my social media over the next few months. I'm not currently active on social media (not sure if I will be within the next 6), so may be she means he will be checking if I'm back on.
