My ex and I split up 5 yrs ago. We had 2 DD's now 9 and 11.
The problem is she (in my mind) always takes the piss, manipulates pick up times and drop off times to suit her. She's always late/changes plans and generally only gives me a "this is what I decided" type call, the kind where I am left feeling like its me who objects, has to say no or is causing the problem.
I find it hard to reason with her because of her past record and so am probably defensive from the off, but even after I calm down and try to respond rationally, by email or text or phone call, I start to get wound up as I feel I am pacifying her.
She seems to think we ought to be friends but IME she does this to everyone so I don't see how being friends or not has anything to do with it.
