How do I move on?

A year ago I was married and very unhappy F(29) when I met M(38) Also married and the connection was the most intense thing I’d ever felt. It wasn’t just that though he became a close friend we spoke most of the day whenever we could every day without fail.

I knew my marriage was coming to an end already and was preparing how to leave all while he was there supporting me.

September 2025 I left my now ex and continued with MM despite knowing he was not leaving his own unhappy marriage I knew it was what it was, despite knowing deep down I should end it because my own feelings were getting very deep and complicated.

I would smile at every message from him any interaction brightened my day, he saved me when I was at my lowest he stopped me from hitting rock bottom.

Fast forward to this weekend talking as normal then I notice last seen has disappeared . No responses came and messages went unread . I reached out one last time Monday and I go back online to discover I’d been blocked no message saying why .. just gone.

I know the whole situation was wrong but to have everything ripped away with no closure, it really hurt and I keep wondering what I did. I loved him and he left me with no answers

To others that have had similar how do you move on with no closure ?
