Children say they don’t want to see me !

I left my x 5/6 years ago due to us both arguing,

I was seeing my kids for a year always had to argue to get to see them but saw them had them stay every week etc then x started to refuse me seeing them ,

Months went on mediation was turned down twice b4 I got to court so at this stage 3/4 months had passed no contact with my children ,

I went to court x played DV card no reports of this b4 no police records nothing , on 1st day hearing she said no further action on the DV as there was none , and change it to DA , cafcass get involved to do sec7 reports all my children said don't want see me ,

Anyway long story short now 4 years down the line I still only have indirect contact ,

Even tho there's been reports and evidence of PA no charges against me no criminal record clean drink and drugs tests , txt message from children saying they want to see me etc etc

Never had a fact finding hearing

the mother will simply not support any contact or move forward and the kids don't want to upset her ,

How do you get to see your kids if they are telling the professionals they don't want to see you
