I definitely remember you & thanks for coming back & updating us.
Firstly try not to read into the future of how things may be & how your son may feel in the future, it will drive you crazy.
Accept that you made a healthy choice for yourself & your family & focus on the now & a brighter future.
Do not hold yourself responsible for the relationship between your son & his father, that is their relationship & you have no control over that.
I'm glad to hear your son is doing better.
Look after yourself, focus on you & given time you will be in a much happier healthier space, I promise.
Big hugs.
