When tapestries of life get tangled in the loom.

"I tried to be agreeable and smile, for nothing it seemed, oh well."

Stop expecting her to have a response.

"Another thing that also prevented me from being super interested in my S in the beginning was the lack of 1. response from him and 2. ran out of things to do with him. It's okay to play at the park for one hour, but the rest of the time ?"

Seriously? Have you read anything that 25 and myself had written about what to do with your son? He's not there to amuse you. You are supposed to be there for him. There are a ton of books on what to do with your child. Even for ones as old as your son. PLUS, it's not important to do something with him. Just BE there with him and spend time together should be enough.

"If good memories resurface for her, and she wants to resume our relationship, I'd be very cautious.
Things went south indeed when the baby was born. So what?"

Again, she doesn't want to go back to your situation because you haven't changed. You keep insisting that you have but your actions speak otherwise. And to be clear, ALL relationships change when a child is born.

"She didn't play it fair, it was all hitting below the belt, meanness of character."

Show us again where she was "hitting below the belt". We all went through this with you but you're not listening. There are parts of truth in the things she wrote. You're just refusing to accept them.

"No stories on her childhood, on her parents or siblings, no lies or exagerations. I'm not proud of it, that's what I expect from anyone a little honest."

Those have no bearing on your son's well-being right now. And from what she wrote, she was being honest.

So what exactly have you learned about your son? When is his next doctor's appointment? Do you know what to do if his eczema or stomach problems come up?
