Christmas D*ck - just a little rant/vent

My son lives with my mom (long story) he’s 17 and his biological father mailed him an Xbox One and 5 games for Christmas. I just learned that today (Dec 24th) and he my ex husband never asked what my daughter would like (she’s 15). So he got one kid a present and is ignoring the other one….. 🙄 let me add this to the long ass reasons why we got a divorce.

Edit** sorry I should have clarified that both are his biological children, my 17 year old and my 15 year old are genetically his children.
