Would I be wrong

If I didn’t count my sons half brother has his sibling. I said earlier to a friend that I couldn’t wait to make my son a big brother and one of her friends there said well he already has a little brother. First off I meant I myself give him a sibling. Second off, his dad is a deadbeat that has absolutely nothing to do with our son and hasn’t since he found out he got his girlfriend pregnant with the child he has now, but even before he didn’t really have anything to do with our son. We don’t talk or anything. He’s not apart of our life at all. My son has never met the other little boy and probably won’t ever meet him because my exes girlfriend hates me because of lies that he put in her head about me. So I don’t really count that my son has a brother or is a big brother because he’s not in that little boys life at all. Am I wrong?? I mean if you get technical yes he does have a half brother, but like I said they haven’t met. My two year old son doesn’t even know about this baby. I didn’t even find out about that baby until she gave birth in August.

I have half sisters as well because of my dad but he is not apart of my life and I don’t see him or them so I don’t even count them as my sisters either.
