Ex wife problems

[Stepparentchallenges]

In my last post complicated advice needed i have explained that I have chosen to ask him to rent a room locally for the time being and to prove himself with regards to money. (Needing some advice on that post about csa) but I am feeling so run down and depressed with everything that I think we need it to be this way so I am only relying on myself and he can actually step up. Anyways my sister for my birthday bought me and my partner a overnight stay at Thorpe Park and is having my eldest for us whilst she arranged for my partners/ex partner (not really sure what we are,)mum to have my youngest son for us. She handed it to me as a surprise after I made the decision I wanted him to move into a room somewhere. I have decided I think it will be good for us to go together, it'll be fun and have some time alone and we can really talk about things too. However this is where the problem comes into it. We have arranged to drop him off to MIL at 10am next Friday and then drive the two hours from hers to Thorpe Park, have our day at Thorpe Park and check into hotel, then Saturday use our second day at Thorpe Park, get to hers for 5.30 and then make the two hour journey back to my house as we have got to collect my eldest son by 8. This was all fine as my partner is due to see the girls this Friday. His ex wife asked the MIl if she could help her out and have the girls next Friday and she explained she couldn't because she has got our son. The ex wife is now kicking off to my partner as we won't be seeing the girls when we come up and dropping our son of, but they will be in school. And if we were leaving our son with her and she lived closer it wouldn't be a issue. He's now trying to say thy maybe we should just miss out the first day at Thorpe Park to keep her happy but am I being unreasonable to think that we shouldn't have to miss it out when it's not our weekend to see them, and it would waste a day of the gift my sister has given. What would you say to him? He doesn't want us to miss the day but she is just keeping on :(

She doesn't need the maintenance, she wants the extra to go out and do more.

So fucking what? She raises those children pretty much without any help from your worthless partner, she's paying for everything else as well.

She IS entitled to a life, it's not her fault she has her shit together and you don't.
