So my ex, the mother of my 7 year old, had her new baby with her boyfriend 2 days ago. Meaning my son now has a baby brother.

My sister, who she talks to from time to time, saw the pictures on Facebook and let me know about it. It’s ironic because my own child’s pictures were all over Facebook 10 hours before I even knew I was a father. Although obviously this isn’t my child so therefore their picture on Facebook means nothing to me.

I don’t really know how I feel. I think I literally feel nothing at all. I mean, I’m happy for my son now being a big brother, but that’s about it. Aside from that I’m completely emotionless about it all, even the possibility of future dynamics changing in ways I don’t and won’t agree with.

I haven’t texted her to acknowledge that I know or to say congratulations. I don’t know if I should do so, or even if I really want to.

Any thoughts on what I should do?
