AITA for wanting ex to recognise my pregnancy despite saying it was fake

Devastated by ex ‘30M’ saying I ‘27F’ faked pregnancy

Ex broke up w me and then I found out I was pregnant- he was keen for me to have a termination and after letting me know that he went pretty much no contact. I was considering keeping the baby and kept to the no contact, but sadly had a miscarriage.

I ended up in hospital with very heavy bleeding and having no one else to call, I phoned him to ask for some help getting home. I told him the bleeding was from the abortion but actually I had a miscarriage - I needed some help and knew he’d be fuming if he thought I was keeping the child - the end result was sadly the same for me and I just wanted an easy life and no acrimony.

Instead of showing up to help, he decided to focus on pursuing the termination providers who had been supporting me through the pregnancy more broadly and they breached my data by sharing information which wasnt correct. As a result, my ex never showed up to help me at hospital and threatened me w legal action after accusing me of having a false pregnancy. He blocked me and sent me hideous messages saying I lied about being pregnant and calling me coercive and manipulative when I’d attempted to be kind/empathetic to him since the days after the break up whilst being very hurt.

I’m working through the grief of my baby with a therapist, as well as the break up, however, something about him invalidating my pregnancy and subsequently my experience with my miscarriage has killed me inside. I want closure and to tell him he’s wrong and share all my medical records to set the record straight with him? Or is it not worth it given he’s been quite abrasive and worried he’ll be punitive towards me?

I’ve been devastated by the loss, the physical impact was horrible and the mental pain and grief is torture - I can’t sleep or eat and I had a nervous breakdown as a result and feel I need some closure and to feel heard - his denial makes me feel like my baby never existed and that’s killing me inside.
