Am I controlling because I don’t want my bf interacting with his ex gf on social media?

They broke up like 2 months before we started dating all within 2022 so I always wondered if he was over his situation.

I didn’t pursue the relationship because of my weariness but he made it clear he was over it.

When we first started dating I asked him not to like her statuses anymore especially when she spoke about relationships or couple things..

He deleted her but I recently saw him add her back on another site ( says he was just unblocking people and once he unblocked her they followed each other no big deal no texts no calls nothing ) and liked two of her pictures one with a flirtatious caption.

I told him again how this made me feel. He apologized but I don’t think He sees the significance in it because he SAYS he doesn’t want her and they would be together if that was the case and he looks as it as I want him to hate his ex.

I don’t complain about liking other girls stuff though all I ask is show your recent ex NO attention.

Edit : we talked and said we would move past things since we have a understanding but I can’t stop thinking about it now like I shouldn’t have forgiven it
