This is long - sorry!
Split up with ex not too long ago and we share a 10 year old DD.
He kept accusing me of just wanting his money (eye roll), so after speaking to DD who was happy to do 50/50, I don't get any maintenance but he pays half the fees of her hobby. I also do childcare in the school holidays and when he occasionally has to work away, so it's not exactly 50/50.
This hobby is competitive and includes a fair bit of travel on occasion. We had one recently which he had already agreed to drive us to (I don't drive and no, it's not because I can't be bothered learning!)
He told me while there that he would not be doing any more travel to these events because it's not his fault I can't drive and he doesn't want to go to them as he's not interested in the hobby. The problem he has is clearly with me, but he wouldn't be able to take her himself even if he was interested because there is prep work he can't do, and to be quite honest DD would much rather it was me.
DD stayed with me last night because we were late back from an event, and we will have another next weekend. I have TOLD HIM the dates of all these from the start of the season, but we were together then so he has obviously not bothered to remember. I politely reminded him she would be staying here the night before as we have to leave at 5.30am.
He said 'yeah another Saturday, will be the same the next week, you only co-parent when it suits you like you always do'.
I told him he was welcome to drop her off to me at 4.30am if he wanted and he replied he wasn't getting into it as if I was trying to start an argument! It's his Saturday but I can't exactly tell her and her team she can't go when it's been booked for months, is compulsory, and he has already been told numerous times about it. If he was still here these things would still be happening as they always have - nothing has changed except he is living somewhere else.
I actually don't think IABU, but this is just an example of how things go and he is so convinced I am wrong and trying to take his time off him. He could have the Sunday instead, no problem, He didn't ask and I wouldn't even have had time to say as it was straight away 'you choosing as always'.
I'm mostly venting, but happy to hear alternative thoughts because at the moment I feel like I'm going crazy and I have 8 more years of this.
