Constant ex problems

[BobsyourUncle23]

I just need a bit of advice / thoughts on my decision. Me and my ex split up over 5 years ago. I cannot call him dad of the year, he was there one minute, then he was not interested and so and so. My DS is 8 now, i have a partner who my DS loves alot. My Ex got married and now is getting divorced due to cheating on his wife who i made friends with after they split. She told me all he did to her, he did to me in the past. He constantly changes addresses, girlfriends, never had a proper job, always complains he has no money but will never stick with a job given to him on a silver platter. His family sticks up for him no matter what wrong he does. Recently he stopped paying child maintenance claiming he lost his job. Over the years he caused me so much grief and trouble i made a decision based on how he treated my DS that he will no longer be seeing him. My DS told me he isn't too bothered about going to his dads as he know he doesn't treat him like a proper dad should, always late picking him up, never buys him anything, let him down on many occasions. Many times i asked my DS whether he wants to go see his dad and he said no. Now, how does that make me a bad mother wanting whats best for my DS and stopping him from seeing his dad, seeing all those women my ex gets with, having no stability in his life, sleeping every weekend at different house. Thats no life for a child. Yet the ex calls me a bad mother. I told him the only way now to see his son is to to court. Me and my partner are getting married this year and he wants to adopt my son. I know my ex will never agree to this and i don't know whats the best way to go about this? Will court decide based on my story and the proof of it? I have many people willing to confirm this and messages, bank statements all sorts?
