My child's father as pretty much cancelled plans and let her down consistly for years.

I've had no other option than to seek legal advice from my solicitor to get an agreement in place that he is happy to stick to.

This is my proposal
He sees her 1 weekend day
He involves himself in her education such as parents meetings and target setting appointments etc
We equally share bank holidays
During school holidays he sees her for 2 days each week
If he needs to cancel or rearrange then I require 48 hours notice

This is pretty much how it's always been until he decided he didn't want to spend any time with her over the summer holidays and regularly changed plans.

He's ignored all my letters stating how important it is for her to have consistency and structure.

He has decided to send a few txts asking such as the following;
'Just so I can clarify are you stopping me seeing her completely untill I agree to your terms of the letter you sent me?'

I replied no that's the opposite of the ideal outcome
'Ok so I can get all the details am I only allowed to see her when you it suits your schedule? '

I'm at a total loss of what to do!!

I cannot stop him however he makes it very difficult.

We NEED something in place and he's totally ignoring all my efforts.

My solicitor says I cannot take him to court as I cannot make him see her.

So now what?????

I really need some advice and I feel all my previous efforts are totally wasted now
