Sending love to those who date Avoidant partners

In the past two weeks, we've been experiencing several issues, and after a particularly intense argument, I realized that our communication had completely broken down, making the problems worse. We had many small arguments, and eventually, I ended things. Soon after, I realized I had made a mistake and tried reaching out to him, even expressing that I still loved him. However, he refused to talk to me after the breakup and had become very avoidant, shutting me out completely. I felt abandoned and deeply hurt. Now, he has disengaged from the relationship entirely and is moving on without me.

I’m struggling to reconcile the two versions of my boyfriend—the one I knew before our issues started and the one I’m seeing now. It’s hard to understand how things changed so dramatically. I find myself wondering if he was just love bombing me initially and then abandoning me, and whether he ever truly saw a future with me. It’s been difficult to make sense of these questions and come to terms with everything that’s happened.
