Serious Illness Is Changing My Relationship With My Partner
Serious illness can change a relationship without changing how much two people care about each other.
Serious illness can change a relationship without changing how much two people care about each other.
One of you may suddenly become the patient and the other the organiser, driver, note-taker or carer. Work, money, housework, childcare and future plans can all shift. Treatment may affect energy, confidence, appearance, touch or sex.
Couples can become closer through this. They can also become more stressed, irritable or distant. Neither response means the relationship has failed.
Notice when partner and carer have become the same role
Practical help can gradually take over a relationship.
If every conversation is about medication, appointments, symptoms and jobs that need doing, it can become difficult to remember how you related to each other before illness arrived.
Where possible, protect some time in which neither person has to be the patient or the carer. It may be dinner, television, a short walk or simply talking about somebody else’s news.
Different coping styles can look like lack of care
One person may want to discuss every fear. The other may cope by staying practical or avoiding conversations until there is more information.
That difference can create painful misunderstandings.
Instead of “you never talk to me”, try saying what you need: “I need ten minutes to tell you what I’m frightened about, and I don’t need you to solve it.”
Intimacy can change for emotional as well as physical reasons
Serious illness and treatment can affect body image, energy, sexual function, desire and confidence.
A partner may also become frightened of hurting the person who is ill, or find it difficult to move emotionally between caring and sexual intimacy.
Affection does not have to begin with sex. Holding hands, hugging, lying together or making deliberate time for closeness can matter too.
Questions about whether sexual activity is medically safe with a particular treatment belong with your healthcare team.
Resentment and guilt can appear together
The person who is ill may feel guilty about needing help.
The partner may feel guilty for being tired, frustrated or missing the life they had before.
Neither person needs to pretend those emotions do not exist. Naming them carefully can be safer than allowing resentment to emerge indirectly through arguments about small things.
Make decisions with each other, not only for each other
A partner may want to protect the person who is ill by taking over.
Where health allows, keep the person affected involved in decisions about their own care, household, finances and family life.
Support can preserve independence rather than replace it.
When talking together is becoming difficult
Sometimes couples get stuck in the same argument or stop talking because every conversation becomes upsetting.
A counsellor or relationship therapist can provide a neutral place to discuss fear, changed roles, intimacy and the future.
Seeking help with the relationship does not mean either person is coping badly. Serious illness can place unusual pressure on even long-established relationships.
