Don’t know what to do

My ex and I started a relationship in April 2024, and it became official in the fall. It ended in late February 2025 after he cheated on me. During the breakup, he even made me speak with the woman he cheated with. He blocked me everywhere immediately afterward, then unblocked me on WhatsApp. Following an argument, I blocked him and asked him not to unblock me on ***.Later, he sent me a T-shirt I had left behind. I had asked him to give it to a friend of mine, but he was extremely rude to her, so I had to ask him to mail it to me.At the end of March, I contacted him about an important matter. He replied coldly after two days. I didn’t respond anymore. Two weeks later, I changed my WhatsApp profile picture. Around the same time, he removed his profile photo—at least for me and those not in his contacts—and made his *** public. I’m still blocked there.Then, 3 weeks ago, he unblocked me on ***—exactly at the same time that his profile went back to private. Mine has always been private. There were no messages and no follow. Now two weeks have passed and still nothing has happened.He has an anxious personality, tends to ruminate, is insecure and prone to projection. He doesn’t let go of past relationships easily and has shown signs of obsessive jealousy—not only toward his own past but also toward mine.Why did he unblock me on *** after three and a half months?Is he trying to find closure, to leave a door open, or is it just something symbolic for himself?What might happen next?Is there a real chance he’ll contact me again?
