Dear Abby: My parents only invited one of my young children on a cruise

DEAR ABBY: I’m a single mother of two children, an 8-year-old daughter and a 9-year-old son.My daughter’s father is involved; my son’s father is not.

I was diagnosed with pulmonary arterial hypertension (PAH) when my daughter was born and given two weeks to live.My condition has markedly improved, and I am on the best treatment there is for it. To safeguard my son in case something happens to me, my parents and I did a third-parent adoption.

And be glad that your daughter’s father is as responsible as he seems to be. DEAR ABBY: I used to hang out with my friend “Brian” and his girlfriend, “Jenny.” We all lived together and would spend almost every weekend together.They broke up and went their separate ways 14 years ago.

Jenny is single, and Brian has a steady girlfriend now.I still talk to them both, but not often. Jenny messaged me recently on social media.

We shared some photos and talked about the past and present.She said she has her own place ...
