Is this a red flag, or is it my anxiety?

A red flag is something the other person keeps doing that you could describe in one plain sentence, and that would bother you even on a calm, well-rested Sunday. Anxiety is an alarm that goes off before there’s evidence, or stays loud after the evidence says you’re okay, and in your 40s there are a lot of reasons for that alarm to be turned up.

Why is it so hard to tell them apart right now?

Meet Jess, 43. She runs a team of twelve, has a teenager half the week, and is training for a half marathon she signed up for in a burst of optimism. Three weeks ago she started seeing someone. He’s funny, he’s attentive, and last Friday he texted “who are you out with tonight?” She told her friends it was nothing. She has thought about it roughly forty times since.

Is that a flag, or is that Jess’s week?

Part of what makes it hard is that midlife is when anxiety is most common. The National Institute of Mental Health estimates that 22.7% of adults aged 30 to 44, and 20.6% of adults aged 45 to 59, had an anxiety disorder in the past year, compared with 9.0% of adults over 60.1 And it has been climbing. In the American Psychological Association’s Stress in America 2023 survey, the share of adults aged 35 to 44 reporting a mental illness diagnosis, led by anxiety and depression, rose from 31% in 2019 to 45% in 2023, more than any other age group.2

None of that means you have an anxiety disorder. Only a qualified professional can say that. It means that if you’re single in your 40s and carrying a lot, your nervous system may already be running warm before anyone new shows up.

What does anxiety do to how you read someone?

It points your attention at threat. In a review of 172 studies, Bar-Haim and colleagues found that anxious people reliably notice threatening information faster and hold on to it longer, a pattern that didn’t show up in people who weren’t anxious.3 In dating, that looks like reading one short reply as coldness, or remembering the one odd question from an otherwise lovely evening.

And anxiety predicts badly. Penn State researchers Lucas LaFreniere and Michelle Newman asked 29 people with generalized anxiety disorder to log their worries for 10 days and then check what actually happened. 91.4% of the worry predictions did not come true.4 That was a small clinical group, not daters. But it’s a useful reminder that a fear’s intensity tells you about the fear, not about the future.

The tricky part: anxiety doesn’t mean nothing’s wrong. Anxious people also date people who behave badly. So the goal isn’t to dismiss the alarm. It’s to check it.

What does an actual red flag tend to look like?

Red flags are about behavior, and they usually repeat. The clearest ones involve control. The CDC describes coercive control in relationships as behavior meant to monitor, control or threaten a partner.5 In early dating, that can look like:

• Wanting access to your location, phone or messages, and sulking or getting angry when you say no.
• Discouraging time with friends, or making you feel guilty for having plans.
• Getting angry in ways that make you careful about what you say.
• Pushing past a no, then acting as if it never happened.

You don’t have to decide what any of this says about who he is. You only have to notice that it’s happening and that you don’t want it.

Then there’s the large gray middle: slow replies, a vague answer about the last relationship, plans that shift. These aren’t flags yet. They’re questions.

How can you test which one it is?

Jess tried three checks. You can borrow them.

The calm-day test. Imagine reading his text on a slow Sunday after a good night’s sleep. Does it still sting? Jess’s honest answer: on a calm day, “who are you out with?” reads more like curiosity than control.

The second-time test. Flags repeat. Anxiety repeats too, but inside you, not in their behavior. Jess decided to watch the next three times she had plans without him. Twice he said “have fun.” Once he asked who she was with, and then said “say hi to Liz.” That’s information. It points toward an ordinary guy with an ordinary question.

The plain-sentence test. Can you describe what happened without adjectives? “He asked who I was out with” is a fact. “He’s checking up on me” is a reading. If all you have is the reading, you have a question to ask, not a verdict.

If Jess had found the opposite, a question every time, irritation when she didn’t answer, the same checks would have told her that too. That’s the point. They work in both directions.

When is it time for more help?

If the worry is constant, keeps you up most nights, or follows you into work and parenting for weeks, a licensed mental-health professional is the right help. That’s true whether or not the person you’re dating is behaving well.

And if someone you’re seeing is monitoring you, isolating you, or you feel afraid of how they’ll react, that isn’t anxiety to manage. Tell someone you trust, and use the support line on this page.

What the research doesn’t show

• Population statistics can’t diagnose you. High anxiety rates in your age group don’t mean your fear is wrong, or right.
• The worry study was small and clinical, with 29 people being treated for an anxiety disorder.
• The attention research is mostly lab-based, using words and images, not real relationships.
• No checklist can read someone’s intentions. It can only help you see their behavior more clearly.

What to do this week

• Pick your answer above and try its next step once.
• Write the fear down with a date. “He’s losing interest” goes on paper, dated. Look again in two weeks.
• Run one of the three tests on whatever is keeping you up tonight.
• Ask one plain question instead of decoding (scripts above).
• Protect one evening that has nothing to do with him. A full life isn’t just a nice idea. It’s what keeps one text from becoming your whole week.
