Ask Z: My Husband Is Battling Brain Cancer, and I Want to Leave Him

Many people believe marriage is about standing by your partner through sickness and health. But what happens when staying begins to cost you your peace of mind? Joy* (32) finds herself torn between wanting to leave her husband and feeling guilty about walking away while he’s battling brain cancer. She needs your advice.

When I met James on Bumble in 2024, I was recovering from a messy relationship. My ex had cheated on me and wasted my time. After taking some time to heal, I joined Bumble mainly to make friends. I wasn’t looking for anything serious until I met James.

From our first conversation, he seemed like a good man. He had many of the qualities I wanted in a partner and made me feel adored. Whenever we argued, he was usually the first to apologise. While I wasn’t head over heels in love with him, I liked him enough to believe the feelings would grow with time.

From the moment we met, James was clear about his intentions. Things moved quickly, and by October 2024, he had proposed. He was 37 and wanted to settle down , so I said yes. We tied the knot in January 2025, less than a year after our first date.

At first, things were fine; we lived comfortably. My only concern was how involved his rich parents were in his life. I sometimes felt they had too much say in our lives as a couple.

However, those concerns paled in comparison to what I began noticing a few months into our marriage. James struggled to sleep and frequently complained of headaches and dizziness. One day, he vomited blood, and I insisted we go to the hospital. He brushed off my concerns, insisting he had everything under control and could manage with medication.

Eventually, he listened to my constant nudges and went to the hospital. I’ll never forget that day. While I was at work, James sent me a message saying he now knew what was wrong with him, but that we would talk about it when we got home.

By the time I got home, James’ eyes were puffy. He told me about the brain tumour he had battled before we met. He had been diagnosed with astrocytoma, a form of brain cancer, and had undergone surgery and radiotherapy in 2022. He had recovered, but now the tumour was back.

When I asked why he had never told me, he said it had simply never come up in our conversations.

I was stunned. We’d gone through the usual pre-marital screenings for hepatitis and genotype;, he could’ve opened up then about his condition. I even remembered asking him about the scar on the side of his head, only for him to laugh it off and change the subject. How could he claim it had never come up?

IBut in that moment, I was too overwhelmed to fully process his decision to hide the diagnosis. My first thought was how to support him. James reassured me that the recurrence had been caught early and that everything would be fine once he had another surgery.

The more I researched his condition, the angrier I became. He had completed treatment in 2022, yet the tumour had returned. Surely he knew there was a possibility of that happening. Why hadn’t he told me before we got married and allowed me to decide for myself whether I was willing to take that risk?

Still, I pushed my feelings aside. I believed marriage meant standing by your partner for better or worse. But as I took on the role of his primary caregiver, I began to realise just how much it would demand of me.

After James’ second brain surgery in January 2026, his employer placed him on medical leave without pay. His savings dwindled, and although his family covered his treatment, I still had to pay for many of our daily expenses. I sometimes dipped into my own pocket to cover smaller hospital bills because I didn’t want to call his parents for every little thing.

The financial strain was already a lot to deal with, but James’ behaviour made things even harder. The affection he once showed me disappeared. He would snap at me, boss me around, check my phone and get angry if I didn’t answer his calls quickly enough.

At one point, I couldn’t afford fuel, so I started getting rides with a coworker who lived nearby. James was upset about the arrangement and kept nagging me until I stopped. I tried to be patient, telling myself that his condition was frustrating him.

It wasn’t until my younger sister visited in July that I began to see things differently. Within days, she had noticed how James spoke to me and pointed out that his illness didn’t excuse his behaviour. Hearing that made me feel validated. When I tried to discuss it with James, he would shut me down by asking if I thought he wanted to be in this situation. Somehow, every conversation ended with me feeling guilty for speaking up.

I also spoke to his mother about our finances and the pressure I was under, but her response only made me feel worse. She pointed out that some women had to run around looking for money to treat their husbands and said all I needed to do was stand by James like a good wife.

I’m not close to most of my family, so I’ve had few people to turn to. Lately, I’ve been struggling mentally and barely recognise myself. I hate that my mood seems to depend on how James treats me. Some days, he’s warm and I catch a glimpse of the man I married. But those moments often come when he’s talking about our future and how he wants us to start trying for children after his treatment.

The truth is, I don’t want that. His final round of chemotherapy is expected to end in November, but that doesn’t mean the tumour is gone for good. I can’t imagine going through all of this again with children to care for, especially when I’m already struggling to hold myself together.

The more I think about it, the more seriously I consider leaving. I’ve decided to wait until James finishes treatment before making my final decision. My mind is already off the marriage, but I don’t want to abandon him while he’s still vulnerable.

What makes this decision harder is how people around me say I’m doing the right thing by standing by James through his illness. Every time I hear these comments, I can’t help feeling that walking away would make me a terrible person. I’m also worried that leaving could set James back in his recovery.

I honestly don’t know what to do. What would you do if you were in my shoes?
