I feel for you as my friend has just been taken through the Courts by her Ex regarding contact with their daughter.
He’s a nasty man, he told lies, he was spiteful it all seemed like he was doing it not with the child’s best interests at heart but purely to try and exert some power and control over my friend.
The good news is that Solicitors see this type of thing all the time and are very skilled in spotting the parents that care about what is best for the child and the parents who are doing it for vindictive reasons.
The Courts set up an arrangement for my friend which tried to meet both their wants but also looked at what was best for their daughter. The Solicitor told my friend that she’d seen hundreds of men just like her Ex, the ones just being cruel and vindictive and they can be spotted a mile off. She predicted that within a few months her Ex would start trying to change the Contact Order to suit him, which he did as he kept wanting to swap the nights and days to fit around his social life.
My friend has now been told that as he is persistently trying to break the order she can return to Court and request it be re-looked at in terms of changing it more to what she think suits their daughter best.
The prospect of going to Court must seem very scary but you can’t continue the way you are. I think you should call his bluff and seek out legal advice. Tell him you’re doing it because you don’t think all the inconsistency and arguing is best for your son and that you want a fixed arrangement in place.
Take back the control OP because that’s what he thinks you will never do. Don’t let him walk all over you and dictate your life like this.
There will be some Solicitors out there on Family Law who offer free sessions of advice (my sister used one when she split with her Ex) so make the first step today and contact one
