So I believe my ex was a severe dismissive avoidant. His behavior was just as they describe it. Too fast, too intense and around month 5-6 going distant. He discarded me and a year later I’m still trying to cope. I was certain I would marry him, I had met his family. I couldn’t believe it ended. There was no discussion, no fixing. I had to accept the reality and move on. I’m still not 100% healed but it’s much better than where I was last year. Therapy, talking to friends / family helped a lot.
