First, this form of communication lacks the majority of what makes up communication. The written word only makes up about 30%. Tone of voice, facial expression and body language make up the other 70%. So, sometimes impressions are misinterpreted.

Your husband is the legal father of your child. The only thing that will change that, is if you remarry and your new husband adopts your son, or if you both give him up for adoption.

A birth certificate is a legal document. Making false statements on a birth certificate can have legal implications, but I don't see that in your case.

So your issue now is a) to get support from his legal father and b) to know for sure what your son's parentage is so he can understand.
