What does this mean???

Hiya, so me and my ex bf broke up back in august but it was a mutual decision because he was moving countries and he decided it would be hard to keep in contact with the different time zones etc. We obviously still loved eachother when we split up and we promised to be friends and still be involved with eachother afterwards but a week later he started deleting me off all socials despite his promise to be friends and involved still. Recently he started adding me on all socials again and hasn’t moved countries. Why is he doing this? Is he just regretting what he did? Is he trying to pretend he never deleted me? Is he looking for an easy shag? Like I need opinions in case he decides to get in contact with me again so Ik if I should reply or leave it be. If u need more details to give advice then I can give them
