I used to think staying friends with an ex meant you never really loved them in the first place.

That changed when I ran into my ex-husband at a coffee shop three years after our divorce.

We ended up talking for an hour about our careers, his new relationship, and my recent trip to Thailand.

No awkwardness and no hidden agenda, just two people who once shared a life catching up like old friends.

That conversation made me realize something important.

The ability to maintain a healthy relationship with an ex isn’t about lacking feelings or being emotionally detached. It actually requires significant emotional intelligence and maturity.

Let me share what psychology reveals about the specific behaviors that make this possible:

1) They process their emotions fully before attempting friendship

You can’t skip the grieving process and jump straight to friendship.

People who successfully maintain good relationships with their exes give themselves time to feel everything first.

The anger, the sadness, the disappointment; they don’t rush through these emotions or pretend they don’t exist.

People who took time to process their breakup emotions were more likely to develop positive post-relationship connections.

When I divorced at 34, I spent months in therapy working through the devastation.

Some days I journaled until my hand cramped, while other days I cried during yoga practice.

This emotional processing was preparation. Only after fully acknowledging what I’d lost could I appreciate what remained.

2) They establish and respect clear boundaries

Mature individuals understand that friendship with an ex requires different boundaries than regular friendships.

They communicate openly about what feels comfortable and what doesn’t.

Maybe that means no late-night texts, perhaps it involves avoiding certain topics of conversation, or agreeing to give each other space when new partners enter the picture.

These boundaries are guidelines that evolve over time.

The key is being honest about your needs and respecting theirs equally.

3) They take responsibility for their part in the relationship’s end

Blame keeps you stuck in the past.

People who maintain healthy relationships with exes have done the work to understand their own contribution to the breakup.

They don’t paint themselves as victims or villains.

Instead, they recognize relationships as co-created experiences where both people play a role.

This doesn’t mean accepting fault for everything or excusing bad behavior, but acknowledging your patterns and mistakes creates space for genuine forgiveness both of yourself and your ex.

4) They separate the person from the partnership

Here’s what emotionally mature people understand: You can appreciate someone as a human being without wanting to be their romantic partner.

My ex-husband is creative, funny, and incredibly loyal to his friends. These qualities didn’t disappear when our marriage ended.

What changed was our compatibility as life partners, not his inherent worth as a person.

People who can compartmentalize these aspects tend to have more successful post-breakup friendships.

They recognize that romantic incompatibility doesn’t erase all the positive qualities they once admired.

5) They communicate with genuine kindness

Every interaction isn’t loaded with subtext or manipulation. People who stay on good terms with exes have moved past game-playing.

They don’t reach out to make their ex jealous, and they don’t maintain contact hoping to rekindle the romance.

Their communication comes from a place of authentic care and respect.

This might look like:

• Sending a birthday text because you genuinely hope they have a good day
• Sharing career opportunities that might benefit them
• Offering support during family crises without expecting anything in return
• Celebrating their new relationships without bitterness

The absence of ulterior motives makes these interactions clean and uncomplicated.

6) They’ve redefined their identity outside the relationship

You can’t be friends with an ex if you’re still defining yourself through the lens of that past relationship.

Mature individuals have done the work to rediscover who they are as individuals as they’ve rebuilt their sense of self that isn’t dependent on being someone’s partner.

After my divorce, I traveled solo for the first time, I rekindled friendships I’d neglected, and I explored interests my ex never shared.

This process of redefinition wasn’t about erasing the past but about expanding beyond it.

When you know who you are outside of a relationship, you can interact with your ex from a place of wholeness rather than need.

7) They practice genuine forgiveness

Forgiveness isn’t a one-time decision. People who maintain healthy relationships with exes understand forgiveness as an ongoing practice.

Some days old resentments resurface.

Memories might trigger unexpected pain, but they choose to release these feelings rather than nurture them.

Studies show that forgiveness is strongly correlated with psychological well-being and the ability to maintain positive post-breakup relationships.

This means choosing not to let past pain dictate present interactions.

True forgiveness creates space for a new kind of relationship to emerge.

Final thoughts

Not every relationship with an ex needs to become a friendship; sometimes the healthiest choice is no contact at all.

However, for those who do maintain these connections, it’s rarely accidental.

These seven behaviors require intention, maturity, and ongoing effort. They demand that we evolve beyond our initial reactions and choose growth over grudges.

My parents divorced when I was 19, and watching them navigate co-parenting with grace taught me early that endings don’t have to be bitter.

Now, years after my own divorce, I see how these mature behaviors have allowed something unexpected to flourish.

Not romance or what we had before, but something valuable in its own right: A friendship built on shared history, mutual respect, and the wisdom that comes from letting go.

What would it take for you to release the story that all exes must be enemies?
