How do I stop being afraid of abandonment?

You stop being afraid of abandonment slowly, by giving the fear new evidence: people who stay, moments where you reach out and someone answers, and proof that you can get through it when someone doesn’t. Being single in your 20s, between relationships, is actually a good time to do that, because you can work on it without a new person’s every move setting off the alarm.

Where does the fear come from?

Usually from experience. Somewhere along the way, closeness and losing it got linked: a parent who was there and then wasn’t, a friend group that dropped you, a first serious relationship that ended without warning. The fear is your mind’s attempt to never be caught off guard again. It isn’t a character flaw. It’s a lesson that was learned too well.

Take Jules, 26. Four months ago her three-year relationship ended, and now that the worst of the grief has passed, she’s noticing something uncomfortable. In the last year with her ex, she checked in constantly, rearranged her plans around his, and went quiet and agreeable whenever he seemed distant. She also did a version of that in the relationship before. Different guy, same Jules.

That’s worth taking seriously, because patterns tend to travel. Using a large German survey, Matthew Johnson and Franz Neyer compared 554 people’s first and second relationships once each had settled in.1 On satisfaction, conflict and how stable the relationship felt, the new relationship looked a lot like the old one, and only two things differed: more sex and more admiration from the new partner.1 A new person doesn’t automatically bring a new pattern. What you bring with you does a lot of the work.

Isn’t it just about who you date?

Partly. Choosing people who are consistent matters a lot. But if the plan is only “find someone who won’t leave,” the fear stays in charge of the search, and it tends to read every slow week as proof.

There’s also some evidence that how hard breakups land is partly a stable tendency. Shmuel Shulman and colleagues followed 124 young adults in Israel from age 20 to 28.2 About two-thirds had consistently low distress after breakups across those years, and about one-third had consistently high distress.2 The people on the low track tended to show skills for handling their relationships competently.2 That doesn’t sort anyone into a box forever. It does suggest that if every ending flattens you, the useful work may be in skills and patterns you carry, not just in the next person.

Can friends actually help with this?

Yes, and this is the part people underrate. In a study of young adults in Italy, friends were a big part of people’s attachment networks, the people they turned to for comfort and to feel close, while parents often stayed the steady base in the background and romantic partners became more central over time.3 The researchers described young adulthood as a period of intense reshuffling of who those people are.3

That reshuffling is your opening. Every time Jules texts her friend Anika “bad night, can I call?” and Anika picks up, the fear gets a data point it didn’t predict. Every time Anika is busy, says so, and calls the next day, it gets another one: people can be unavailable without leaving.

Can the fear really change, or is this just who you are?

It can shift. In one study, psychologists Carnelley and Rowe used brief exercises designed to activate a sense of attachment security, repeating them on three occasions over three days.4 Two days later, without any reminder, those people reported less attachment anxiety, more positive views of themselves and more hopeful expectations of relationships than at the start, while a comparison group showed no change.4

That was a short lab study, not a cure. But it fits the bigger idea here: security builds through repetition. Not one big revelation, but lots of small moments where being close went okay.

Is therapy worth it if you’re not in a relationship?

Often this is the ideal time. A meta-analysis by Kenneth Levy and colleagues pulled together 36 studies with 3,158 patients.5 People who were more securely attached tended to do better in therapy, and improvements in attachment security during therapy may go along with better outcomes overall.5 For people starting out less secure, therapy that focuses on relationships and how you interact with others may be a particularly good fit.5

You don’t need a crisis to go. “I want to understand why endings hit me this hard before I date again” is a perfectly good first sentence. And if the fear is intense, constant, or getting in the way of your sleep, work or friendships, a licensed mental-health professional is the right help, not something to push through alone.

What to do this month

• Write the last-relationship timeline. What happened in the final few months, and what did you do each time you felt them pull back? One line per moment.
• Name your move. Chasing, shrinking, going cold, leaving first. Most people have one favorite. Knowing yours is half the work.
• Pick two steady people. Friends, a sibling, a cousin. Reach out to them on purpose when you’re low, and notice when they show up.
• Let small disappointments happen. A friend who cancels and reschedules is evidence too. Track the reschedule, not just the cancel.
• Look into therapy if the fear has followed you through more than one relationship. Ask specifically about working on attachment and relationship patterns.

What doesn’t the research show?

• The relationship-pattern study compared settled phases of two relationships in one country’s survey. It shows dynamics often carry over, not that yours will.1
• The breakup-distress study followed a small group in Israel and describes tendencies, not fixed types.2
• The attachment-network study was of Italian young adults and describes who people turn to, not whether friends reduce fear of abandonment directly.3
• The security-priming study was short and lab-based. Its effects lasted days, not years.4
• The therapy meta-analysis is about patients in treatment, and it links security and outcomes without proving one causes the other.5
