Dear Annie: Two and a half years ago, as my business was good, my marriage of 30+ years wasn’t.

It was that same old case of drifting apart due to the pressures of life. Our kids had left home except for one, and we looked at downsizing. We signed up for a new apartment, so we had to get our house ready for sale.

My wife and I had this huge fight, we’d had these before, and our relationship was becoming toxic for me, so when we had this fight I finally called it a day. We did counseling but instead of getting us back together, it was suggested we separate, much to my now ex’s disgust.

I had to stay at the house as I was renovating it, which made it difficult. A few months later, I’d met my now-partner, who is much younger than me. We fell for each other pretty quickly during that period in which I was still at the house but my wife and I were over. A few months later, my now-partner became pregnant.

No one knew about my new relationship. In November, my wife and I told the kids we were separating, and, naturally, they were upset. I moved in with my partner to look after her while she was pregnant but still kept her and the pregnancy secret.

After Christmas this year, I told my ex and my kids about my partner, but not the fact that she was pregnant. My ex didn’t take it well at all. My eldest daughter and youngest son took it pretty well, but my middle daughter took it the hardest. Based on her reaction, I was afraid to tell them anything else and, as such, my new daughter is a secret.

I’ve agonized over telling them, and know I must tell them very soon.

My daughter turned 1 the other day, and it was sad because her half siblings missed out.

My ex had been to a clairvoyant who told her that she saw a newborn, and the day after my ex asked me, “Is this girl pregnant?” I was stunned.

Part of the reason why I haven’t said anything is because I care for my ex and know she will take it very hard. She has a lot of animosity towards me, as does my middle daughter.

I think I’ll need to tell them one by one, with my ex finding out last. — Fearful Father

Dear Fearful: It’s time to rip the Band-Aid off so that the real healing can begin. Your plan, to tell each of your children and then your ex-wife, individually, about your new daughter, is a good one. Be sure to execute it swiftly, all on the same day, as word will travel fast.
