Is 6 months too long for any hope?

Your h is just digging himself a big, deep hole of being a crap dad.

My counsellor said to me (when I was complaining about my h's actions and how much they were affecting d7) that I had to step up and be the parent. No amount of complaining would change things, it was up to me to fill both mum and dad shoes at that point in time. We have been separated for 2.5 years and it's still a roller coaster ride. He doesn't want to let go but he seems to be unable to put the work in that I need to see from him to know he is serious and not just wanting me as a 'teddy bear'.
