Look up trauma bonding
Excellent point & here is a good place to start -

OP, your healing is being arrested by your continued contact with Ex. You cannot begin to recover until he is out of your head so that you can think clearly again.
I know this is easily said, but harder to do.
As you cannot simply tell your feelings to change, & your emotions are understandably a rollercoaster right now, I suggest you take control by implementing some practical steps.
I find myself on the phone to him, sobbing my heart out, practically begging him to try again.
THIS has got to stop my dear. (See trauma bonding).
For your own mental health, you need to be as Low Contact as can be managed.
When you are Low Contact, you reduce the opportunities for him to bitch at & control you further with tactics like -
He’s made comments before along the lines of “get your own friends” “stop trying to be friends with my mates” etc etc.
Also -
I’d also become close to a lot of wives/partners of his friends and feel that now I will have to distance myself.
This is classic narc behaviour - believing that he owns those friends, that they are his puppets & he gets to control who interacts with them. It's bullshit, They are your friends! - you made them, you developed relationships with them, & he has no business telling you who you are "allowed" to associate with. It is just another cliche from "The Script" abusers use to isolate their prey.
You can implement the Low Contact by buying some Co-Parenting software & making the firm decision that, from now on, all communication with Ex is via that platform alone & - brace yourself! - you can then delete & block him on all socials & your phone/email.
Get the software, advise him that this is for DC comms only, then ... take the plunge & block him everywhere else.
He is likely to kick up a stink, but you won't hear it, because you will have blocked him. And believe me - if he thinks the only way he can get at you is via the Co-Parenting software, he will use it.
This leads into the next practical step, which is managing his contact time with DC. It's no surprise that he is messing you about - he does it because he believes the world revolves around his whims, but of course he also does it to upset & control you.
So your next step is legal: you need court-ordered contact days so that he can no longer mess you about.
He doesn't turn up/asks to re-arrange? Tough, He missed that contact, & has to wait for the next one.
Co-Parenting software is your friend here again.
It will hold the contact schedule info, & record all messages.
It will show a pattern of who is the reasonable parent, facilitating access & ensuring DC is available on time - & who is flaking out. It will prove that you have a schedule for contact, & that he needs to adhere to it or lose out.
Any abusive or manipulative messages he sends you there will be stored - along with all the polite & reasonable communication from your side.
It IS over OP - you have to start acting like it is.
You have to protect yourself by going LC, transferring all contact to a Co-Parenting platform, blocking him elsewhere, & getting a legally binding contact schedule set up.
