You sound so absolutely lovely, please don't feel there would be a pile on. You are processing, it's an awful lot to take in, I think you know what you are going to do, you are just a bit shell shocked
I for one and making no judgement whatsoever about you seeing him, I think it is really brave of you to be so honest.
I also completely empathise on the weird feeling of knowledge once you have requested a Claire's law. I stayed for another month after my disclosure, I couldn't get out of my head that they only disclose if they feel he is a risk to you. Additionally you know you've doubted him, and done something to find out about his not personal information, and you can never tell him that.
He may well have been playful, but your seed is sewn now, and you will read in to everything he does
Don't worry about judgment, carry on being honest, and keeping people close
You don't live with him, your child is not involved.
