How to navigate a friendship when a couple splits up – without taking sides or getting caught in the middle

The four of you have been friends for years. You’ve shared holidays, birthdays and countless dinners. Then one evening, a friend calls to say her marriage is ending.

You listen, offer sympathy and ask what she needs. But afterwards, the questions begin. Can you still invite her former partner round? Should you mention that he called? What happens to the weekend away you had all planned?

A separation changes the lives of the couple involved, but it can also unsettle the friendships around them. Familiar arrangements become difficult, and ordinary contact can start to feel like a declaration of loyalty.

Sue Evans, Clinical Practice Manager at Relate at Family Action, explains that although wanting to help is natural, choosing sides is not always necessary or useful.

“The goal is usually to be supportive, respectful and boundaried, while recognizing that every separation is different,” Sue tells Psychologies. 

Be honest about what is possible

You may hope to remain equally close to both people. Whether that works will depend on the circumstances, their feelings and your own capacity.

Evans explains that amicable separations can allow mutual friendships to continue. Where conflict is intense, however, maintaining both relationships may become difficult or emotionally draining. What feels possible initially may also change.

Consider whether both friends are comfortable with continued contact, whether interactions can remain respectful and whether there are any concerns about safety or manipulation.

Evans suggests being transparent: “I care about both of you and would like to maintain my friendships with each of you if that’s possible.”

That expresses your intention without promising an arrangement you cannot guarantee. You may also discover that one friendship naturally becomes closer than the other.

Offer company without becoming a go-between

There are many ways to support someone through a separation. You can listen, share a meal or make space for an afternoon when they would appreciate company.

The difficulty comes when support turns into managing communication between former partners.

Perhaps you are asked to pass on a message, explain what the other person meant or reveal whether they are seeing someone new. Agreeing may feel helpful in the moment, but it can leave you carrying responsibility for conversations that belong elsewhere.

Evans recommends listening without trying to solve the situation, acknowledging feelings without becoming a judge, and declining requests to relay messages.

“I want to support you, but I don’t want to be put in the middle,” is one response she suggests.

Be equally careful about sharing information. An apparently harmless update about someone’s plans or private conversation may create distress or further conflict.

Say where your boundaries are

A friend who is hurting may interpret continued contact with their former partner as a rejection. That can be painful, particularly when you are trying hard to support them.

You can acknowledge their feelings while being clear about your position.

Evans suggests: “I care about you and want to support you, but I’m not comfortable being asked to choose between people I care about.”

Confidences can require boundaries too. There is a difference between listening privately and agreeing to hold information that affects someone else’s wellbeing.

“I’m not comfortable holding that information if it affects someone else’s wellbeing,” Evans advises.

Clear, consistent responses give people a better understanding of what they can ask of you. You don’t need to renegotiate the same boundary every time it arises.

Take surprises out of social occasions

Invitations can become especially sensitive. A birthday dinner that once required little thought may now involve separate conversations.

Evans recommends asking privately about attendance, allowing people to decline without pressure and avoiding surprises if both former partners will be present.

Give each person the information they need to decide whether attending feels manageable. Resist treating a gathering as an opportunity to bring them together or demonstrate that everyone can still get along.

Arrangements may need to evolve. Someone who cannot face a shared celebration now may feel differently later.

When safety changes the situation

Neutrality has limits.

If a friend discloses domestic abuse, coercive control, stalking, intimidation or fear for their safety, Evans says the priority becomes safety and wellbeing.

“This is where neutrality can become inappropriate.”

Take disclosures seriously, listen without judgement and avoid demanding proof. Encourage specialist support, respect safety planning and avoid sharing information that could put the person at risk. If there is immediate danger, emergency assistance may be necessary.

Maintaining the same relationship with both people may no longer be appropriate.

Allow room for your own feelings

You may be losing something too: a familiar group, shared traditions or a friendship that changes despite your efforts.

Evans acknowledges that friends can experience grief when cherished relationships break down. Give yourself time to process that, without expecting either separating partner to take care of your disappointment.

You can be thoughtful, dependable and clear about your limits. How the friendships develop will also depend on the other people involved, and you cannot carry that responsibility alone.
