I'm not going to attend my son's 1st birthday
Is there a good reason behind that?
I just found out I am not his real father, goddamn it.
You have the right to feel that way. Finding out that you're not the kid's father is brutal. You should stay away from all that drama and be at peace.
I still want to know what happened. This is overbearing.
You should wait until after the birthday party to find out. It would be bad to cause a scene at the party.
