My (38F) husband (44M) and I have been married for just over two years. Before our relationship, he was married to a woman named Lexi (43F). They met in their twenties and were together for nearly a decade, including seven years of marriage.

During their time together, Lexi was diagnosed with cancer. He supported her throughout the entire journey until she eventually recovered. Not long after her recovery, she expressed a desire to explore life independently, which ultimately led to their divorce.

Several months ago, Lexi reached out to him. The three of us had dinner together, and I found her to be warm, kind, and easy to talk to. Shortly after that evening, she asked to speak with him privately. During that conversation, she revealed that her cancer had returned. This time, the outlook was more serious, and she confided that she did not think she could go through treatment again on her own.

My husband told me everything, and I supported his decision to be there for her. I even offered to help, but Lexi gently declined, saying she did not feel comfortable being that vulnerable around someone she did not know well. I respected her honesty and stepped back.

As time went on, my husband became increasingly involved in her care and emotional well-being. At first, I tried not to question it. I understood how much she was going through and how much their shared history meant. However, as the weeks passed, it became clear that something had shifted. His presence in our shared life began to fade, and I could feel the distance growing.

Two weeks ago, he sat down with me to have an open conversation. He assured me that nothing romantic or inappropriate had happened between them, but he also admitted that the level of support Lexi needed was not something he could provide while also being a husband to someone else. He said he believed we should separate, at least for now, and that he would understand if I chose to move forward with a divorce.

He left our home shortly afterward, and we’ve had very limited contact since. I’m torn about what to do next. Part of me feels like I should ask for a divorce and start moving on, but another part wonders if I should wait and see how things develop.
