Hey Carman
He is just doing what A's do. He is looking to use you.
When I was drinking I pulled stunts like this, I would use whoever was likely to respond to what I wanted at the time. I would say whatever I knew the person wanted to hear. Make promises (lie) that I thought they wanted to hear.
Save yourself heartache and remove him from your life. Best advice would be not to reply at all. Any reply you do give will be grasped onto and used to manipulate.
You deserve so much better than this. All the best to you.
