So it went well, son had a good 4 hours out with his dad, they went go karting, ex phoned me after he had dropped son off and chatted for nearly an hour, said he was checking if son was ok etc. ex seemed more relaxed on the phone today and actually sounded more like his old self. still have zero expectations because I feel thats all I can have right now,. do really hope they make a relationship for themselves again, we will take it at a steady pace for now, but at least they have made contact and it as been 2 1/2 years
