he has said that he will not reply to my emails and that he has put them into his junk mail so he doesn't see them! I prefer email for the reasons you have stated there is a record and the message is clear and straight to the point no passing info around.
Not your problem if you communicate with him and he chooses to ignore you. You let him know ONCE that this is the ONLY way you will communicate, he can take it or leave it. You're allowing him to control you.
I have pushed for a set schedule hence the asking for his rota so we could figure out days he is available to have him and days he isn't. but he is saying he will not tell me his rota as the days he isn't working he needs to have a life so it's not my business.
Fine, he won't let you know, you set up a schedule that works for you. If he doesn't like that tough. Again, you set the schedule far enough in advance that, given that he knows his rota, he can request adjustments in enough time that it doesn't disrupt your plans.
just an example of the way he is here so I had asked 3 weeks ago if he could have our son on the 13th 14th 15th because my mum was in hospital getting cancer treatment and yesterday he had a go at me for asking him to look after him on those days! btw he only had him for 24hrs from the Sunday at 2 till Monday at 2 as he didn't want him on the other day and didn't want him any later on the Monday. now he had a go at me when dropping our son off that I ruined his plans etc etc even though I have him 3 weeks notice and also didn't know he was in a relationship so didn't think I was doing wrong but in his head I was.
Well, first don't ever depend on him for childcare. I'm sorry, but that's the way it has to be. You should be able to, but you can't. And if he kicks off at you, you walk away or put down the phone. You do not have to take verbal crap from him. His 'life', his 'plans', his 'relationship', his 'head' are not your concern. I don't know if he's programmed you to accept his abuse or if you are just a glutton for punishment, but there are so many ways you can take back your life and you just aren't doing them.
I am more than done trying to get him to be a father he know where my son is he knows when his daughter is due and he knows my email/phone number if he is unable to deal with it then it will be lawyers.
Atta girl! Now stick to that. Frankly, I'd see a lawyer now. Not to start anything, but to get a good idea of what your options and legal responsibilities truly are.
