Really good question and I've often pondered that maybe I'm caught up in the push/pull, hot/cold dynamic. Maybe I'm addicted to the honeymoon phase after a reconciliation??? I'm not sure to be honest.
Before this relationship I was in a 4 year long relationship with the woman I met after my first marriage ended. She was very emotionally absent. I would typically see her once a week. She was definately an avoidant. This relationship was mostly about sex, I believe. We were sexually compatible but not much beyond that.
