The group chat goes quiet. The people you see at weekends turn out to be your partner's friends. Saturday comes and there's nobody obvious to call. Starting again feels like something you should have sorted by now.
It isn't just you. Phone records show the number of people we call falling as we get older, and faster for men than for women. Evidence: decent Calls are a stand-in for friendship, not a measure of it. One American poll says men report fewer close friends than a generation ago. Evidence: worth trying That's a poll, not a study, but it points the same way.
Two things work against you, and neither is about personality. A friend takes time: one paper put it at dozens of hours of hanging out to go from acquaintance to friend. Evidence: decent At school nobody had to plan those hours. Now nothing hands them to you. And your head misjudges the start. After meeting someone new, people underestimate how much the other person liked them. Evidence: decent And they expect a catch-up message to be less welcome than it is. Evidence: decent Both mistakes point towards doing nothing.
What's oversold: you'll read that the brain has room for exactly 150 relationships. The idea of layers, a few close people and more further out, is a reasonable way to think about it. Evidence: worth trying The fixed number is shaky: one reanalysis got averages from 16 to 109, with error margins running from 2 to 520. Evidence: worth trying You'll also read that men bond side by side and women face to face. That came from a 1982 paper, and its author later softened it. A loose tendency at most. Evidence: worth trying Neither changes what to do.
Keep the ones you have
It's cheaper to keep a friend than to make one. Most of the work is not letting them lapse.
Friends
Send the message you're not sending
The friend you've been meaning to contact: two lines, now. Thought of you, no need to reply.

A standing slot with friends
Same people, same time, every week or two. Football, a walk, a pub, a game. Put it in the calendar as a repeat.
2 hours a weekEvidence: decent
Friends
Games night, monthly
Cards, board games, chess, poker. Same people, fixed date, rotate the game.
3 hours a monthEvidence: worth trying
Go where the same people turn up
From zero, the first job isn't finding a friend. It's being in the same place as the same people, again and again.
Friends
Join something that repeats
Look up one thing near you that meets every week without you organising it. A club, a team, a volunteer shift, a class you stay after for a coffee. Go to the next one.

Friends
Do something for someone
Coach, fix, drive, volunteer, mentor. A regular slot, not a one-off.
1–2 hours a weekEvidence: decent
Friends
Talk to the cashier
Small talk with people you don't know. The barista, the neighbour, the man at the next bench. Thirty seconds.

Turn an acquaintance into a friend
Knowing someone by sight isn't a friendship. Somebody has to suggest a thing outside the usual setting. Make it you.
Once you have one, going deeper is a different skill: telling a friend you're not OK, and being there when he's struggling. If you want friends because you're carrying something alone right now, start with Fighting your battles alone.
Friends
They liked you more than you think
Got on with someone new? Assume it went better than it felt. Message them and suggest one specific thing.

Book the next one before you leave
With someone you'd like as a friend, suggest the next meeting before this one ends. Keep suggesting until they start doing it too.

Add a friend at the big changes
New job, a move, a baby, retirement. In the first three months, pick one person from the new setting and suggest something specific. Then again a fortnight later.
