I'm trying to make sense of a relationship that to be honest destroyed my sense of well being.
I now recognise that he love bombed me, ran hot and cold, seemed to have demand avoidance behaviour (but could change seemingly randomly). For example when we were initially in a relationship was extremely hard work communication wise. Insisted that he could not have regular normal contact because he was working. Seemingly unprompted at a later time, would call me every day and answer texts etc 
He is very socially anxious, in some ways but not others. He insisted he was autistic, is this believable according to anyone with experience?
I am so much better in not obsessing over him, he seems like a distant dream rather than an all encompassing drain on my thoughts. Certain niggles still annoy me though.
