Boundaries With Exes — What's Reasonable

Your partner still talks to their ex. Maybe it's occasional texts. Maybe it's regular catch-ups. Maybe they're in a shared friend group and proximity is unavoidable. Whatever the format, it bothers you — and you can't tell whether your discomfort is reasonable concern or irrational jealousy.

The answer, annoyingly, is: it depends. Ex-contact isn't inherently wrong, and discomfort with it isn't inherently jealous. The question is where the contact falls on the spectrum between genuinely harmless and genuinely concerning — and what boundaries you need to feel secure.

When Ex-Contact Is Fine

Co-parenting. If they share children, contact isn't optional — it's required. The boundary here isn't "no contact" — it's "contact that's about the kids, not about the relationship." Logistics, schedules, school decisions — these are appropriate. Emotional processing, late-night calls about feelings, using the kids as a pretext for prolonged conversation — these cross the line.

Shared friend groups. They'll see each other at parties, gatherings, group dinners. This is life, not a choice. The boundary: friendly interaction in group settings is fine. Private, one-on-one meetups that exclude you are worth discussing.

Occasional check-ins. A birthday text. A congratulations on a life event. A brief "hope you're doing well" every few months. Minimal, surface-level, and transparent. If you know about it and it doesn't consume emotional energy, it's probably harmless.

A genuinely platonic friendship that predates and survived the romantic relationship. Some people transition from romance to friendship cleanly and genuinely. This is rare, but it exists. The test: would the friendship look exactly the same to an observer who didn't know they'd dated? If yes, it's probably real.

When Ex-Contact Is a Problem

Secrecy. The single most reliable indicator. If the contact is hidden, minimised, or discovered rather than disclosed — it's a problem regardless of the content. "I didn't mention it because it was nothing" is the universal justification for hiding things that aren't nothing.

Emotional intimacy. They share things with their ex that they should be sharing with you — worries, dreams, daily experiences, emotional processing. This is the emotional affair pathway. The ex is fulfilling a partner role without the label.

Comparison. They reference the ex in ways that suggest ongoing emotional attachment: "My ex used to do that." "Things were easier with [name]." Active comparison means the ex occupies active mental real estate.

Frequency and timing. Daily texting. Late-night messages. Contact during emotionally vulnerable moments (after a fight with you, during a personal crisis). The frequency and timing suggest emotional dependency, not casual friendship.

Your gut. If something about the contact feels wrong — not "I'm jealous of any attention they give anyone" wrong, but specifically and persistently wrong about THIS connection — trust it. Your gut is reading signals your conscious mind hasn't catalogued yet.

How to Set the Boundary

Start with your feelings, not their behaviour. "I feel uncomfortable with how much contact you have with your ex. Can we talk about what boundaries would help us both feel good about it?" This is an invitation, not an indictment.

Be specific about what bothers you. "I'm fine with occasional texting. I'm not comfortable with weekly dinners alone." "I don't mind group hangouts. I do mind late-night phone calls." Specificity prevents the conversation from becoming abstract. It gives both of you concrete parameters to work with.

Ask for transparency, not elimination. In most cases, the solution isn't "never speak to them again" — it's "keep me informed about the contact so I don't have to wonder." Transparency reduces the imagination spiral that drives jealousy. When you know what's happening, your nervous system can relax.

Listen to their perspective. They may have legitimate reasons for the contact. They may not realise how it affects you. They may be willing to adjust once they understand your concern. Give them the chance to respond before escalating.

What's NOT Reasonable to Ask

"Block your ex completely." Unless the ex is harassing you or them, demanding total elimination of a person from their life is controlling, not boundaried. You can ask for limits. You can't demand erasure.

"Choose: me or them." Ultimatums about friendships rarely work and often backfire. If the friendship is genuinely problematic, the solution comes through conversation and boundary-setting — not through an either/or that makes you look controlling regardless of whether your concern is valid.

"I want to read all your messages with them." Monitoring their communication is surveillance. If you need to read their texts to feel secure, the trust problem is bigger than the ex problem — and surveillance won't solve it.

When They Won't Respect the Boundary

If you've expressed your discomfort clearly and specifically, they've acknowledged it, and the behaviour hasn't changed — you're dealing with a boundary violation, and the guidance from Your Partner Keeps Crossing Your Boundaries applies.

The specific concern with ex-boundaries is this: a partner who won't adjust their ex-contact despite knowing it hurts you is making a choice about priorities. They're prioritising that connection over your security in the relationship. That's information you should take at face value.
