Advice needed operation preventing handover with ex

[AKP79]

I am no longer a 'lone parent', but I am still navigating separated parenting issues so I'm hoping this is the right place to post.

I have a court order which stipulates that I have to meet my ex halfway for handovers. The halfway point is over one hour away. However, I am pregnant now and will have to have an elective C-Section which could mean not being able to drive for up to 8 weeks. The Sunday pick up will be fine because my partner can do this, but I won't be able to take my son on the Friday and my partner will be at work until late.

My ex is completely unreasonable and it is like talking to a brick wall half the time so having an adult conversation will be impossible. Does anyone know where I stand legally on this?

For the record, I fully agree with OP as my ex is exactly the same and absolutely WOULD force his rights and relish in my inabilities! He threw me out of the house in an argument when I was heavily pregnant, bed bound and on a catheter! Some men (& women too I'm sure) REALLY don't care WHAT people are going through/suffering with.
