Six People Who Are Quietly Wrecking Your Network

You know all six of them. You just have never named them.

Most advice about networking assumes the problem is you. That you are not reaching out enough, not showing up, not following up. Sometimes that is true. But a lot of the friction in your network comes from other people, and specifically from six behaviors that show up again and again. Once you can name them, you stop blaming yourself and start handling them well.

The Instant Friend

This is the person who becomes extremely close to you extremely fast. Within a week of meeting, they are texting you every day, inviting you to everything, and talking like you have known each other for years. It feels flattering and fun. Then, just as suddenly, they go quiet, because they have found a new person to do this with. You were not special. You were the current one.

The reason it feels off is that real closeness cannot be built that fast. Tracking hundreds of new relationships, communication researcher Jeffrey Hall found it takes about 50 hours together to become casual friends and more than 200 hours to become genuinely close. Anyone skipping straight to best friend in a few days is performing closeness, not building it.

The Asteroid

This is the person who disappears for years, then suddenly reappears in your life as if no time has passed. They call out of nowhere, want to meet immediately, are warm and full of promises about staying in touch, and then vanish again for another few years. The cycle repeats for decades.

What they misunderstand is that friendships need regular upkeep to stay alive. Robin Dunbar, who studies how we maintain relationships, describes friendship as a set of layers of roughly 5, 15, 50 and 150 people, and his research shows that when you stop investing time in someone, they slide down a layer within about six months. So the Asteroid is not keeping the friendship going. They are just checking that a memory still exists, then leaving you to do all the actual maintaining.

The Social Leech

This is the person who only ever contacts you when they need something. Can you introduce them to someone. Can you look over their work. Can you make a call for them. The requests keep coming, and there is always one more. But they never ask how you are, and if you needed something back, they would be strangely unavailable.

Psychologists call this a one-sided relationship, and the research on carrying all the effort in a friendship shows it reliably leads to exhaustion and resentment. The hard part is that nothing dramatic ever happens to justify pulling away. The requests just quietly pile up while you get nothing back.

The Ghost

This is the person who clearly has a problem with you but refuses to say what it is. They stop replying. They avoid eye contact. They physically leave a room when you enter it. You never get an argument or an explanation, just a slow, silent withdrawal that leaves you guessing at what you did wrong.

Avoiding the conversation feels easier than having it, but it does not resolve anything. The psychologist John Gottman, who spent decades studying why relationships fall apart, identified this kind of shutdown as one of the strongest predictors of a relationship ending. The issue stays unspoken, and because it is never named, it can never be fixed or forgiven. What could have been a five-minute conversation becomes a permanent standoff.

The Intruder

This is the person who uses you to get to other people. They attach themselves to you at an event, act like you are close friends when you barely know them, and then use that fake closeness to reach the important people in your network, often without asking you first and without giving you any credit.

There is a good version of this behavior. Introducing people to each other is one of the most generous things you can do, and it works because you are lending your trust, not just handing over a name. A good connector asks first and makes sure both sides want the introduction. The Intruder skips all of that. They do not ask you, they do not ask the person they are angling to meet, and they take the credit either way. Your network is not a public waiting room. It is something you built, one relationship at a time, and you are allowed to be deliberate about who you lend it to.

The Vague

This is the person who always says you should get together but never makes it happen. Every time you run into them it is “we have to catch up” and “coffee soon,” said with total sincerity. But no date is ever proposed, no plan is ever made, and nothing ever happens. The warmth is real. The follow-through never comes.

There is a well-established reason for this. Psychologist Peter Gollwitzer’s research on goal setting found that a general intention like “I want to see them soon” rarely turns into action, but pairing that intention with a specific plan, a fixed time and place, makes people roughly three times more likely to follow through. “Soon” is a goal with no plan attached, which is exactly the format research shows is most likely to fail. The people who stay connected are not friendlier than everyone else. They are just the ones who name the Tuesday.

What to Do About Them

You cannot change how these six behave. You can only change how you respond, and that starts with recognizing the pattern instead of taking it as proof that something is wrong with you.

Keep track of who you have met and what you last talked about, so a returning Asteroid does not catch you blank. Notice which relationships only ever run one way, and stop pouring energy into them. When someone says “soon,” be the one who picks the actual date. Relationships do not survive on good feelings alone. They survive on memory, attention, and the small, deliberate follow-through that turns a nice moment into a real connection.
