“My wife’s ex is back and their love rekindling, what do I do?”- Olumide Adeyanju

I am completely lost and need advice. My name is Olumide Adeyanju(Not my real name), and I’m a 42-year-old civil engineer based in Lagos. I’ve been married to my wife, Tola, for seven years. We have a son together, Jidenna, who is five years old. Our marriage hasn’t been perfect, but I thought we had something solid—until recently.
When I met Tola, she was a divorcee. She told me her first marriage to a man named Dapo Olatunji ended after three years due to irreconcilable differences and I believed her. According to her, Dapo had anger issues and was overly controlling. She said she left the marriage to protect her mental health and focus on building a better life for herself. At the time, I admired her courage, and we built a beautiful relationship.

Last month, everything changed. Tola and I were invited to a wedding in Lekki. As fate would have it, Dapo was also at the wedding. It was the first time they were seeing each other in nearly 10 years. I noticed they exchanged pleasantries, and while it seemed cordial at first, something about the way they looked at each other didn’t sit well with me.
In the weeks that followed, I started noticing subtle changes in Tola’s behavior. She began acting distant and spending more time on her phone, often smiling at her screen like a teenager in love. When I asked her what was going on, she brushed it off, saying it was just “work stress.”
Then, two weeks ago, I came home early from work and found her on a video call with Dapo. She didn’t realize I was home, so I overheard parts of their conversation. They were laughing and reminiscing about their past together things like how they used to travel to Abuja for weekend getaways and the time he bought her a surprise gift for her birthday. It felt like I was intruding on a private moment between lovers.
When I confronted her, she admitted that she and Dapo had been talking regularly since the wedding. She claimed it was “nothing serious” and that they were just “catching up as friends.” But I don’t believe her. Her behavior has changed so much. She’s more secretive, and I even found out she met up with him last Saturday without telling me. She said it was a “closure” meeting, but why does she need closure after all these years?
Now I’m stuck. I love Tola, but it feels like her heart is being drawn back to Dapo. I’ve spoken to my elder brother, Kunle, and he thinks I should stand my ground and fight for my marriage. But my best friend, Tunde, says I should let her go if she’s already emotionally checked out.
I don’t know what to do. Should I confront Dapo directly? Should I give Tola an ultimatum to stop talking to him? Or should I quietly walk away and let her decide who she really wants to be with?
Please, confluencers, I need your honest opinions. Have you experienced or heard of a situation like this? How do I handle it?
