What to Do When She Says “I’ll Let You Know”
“I’ll let you know” hands the next move to her. Your job is to accept that gracefully, and then actually let her make it.
Reply once, lightly, and leave it with her: “Sounds good, just shout when you know.” Then carry on as normal. Don’t ask again, chase a date or check in about it. If she’s keen, she’ll come back within a few days with a time or a question. If a week passes and she hasn’t mentioned it, treat it as a polite no for now and don’t raise the plan again unless she does. Your relaxed response is the most attractive thing you can offer in this moment.

What “I’ll let you know” usually means
- She’s genuinely unsure of her schedule and will confirm when she knows. Most likely if she sounds warm and adds a reason (“I might be working Saturday”).
- She wants to say yes but not commit yet, because she’s unsure about meeting or about you.
- She’s keeping options open in case something else comes up.
- It’s a soft no. Some people prefer to let a plan fade rather than decline directly.
Tone and follow-through separate these. A warm “I’ll let you know!” plus continued chatting is very different from a flat “I’ll let you know” and a quiet conversation.
Read how she said it
- Warm, with a reason, and she keeps chatting: probably real. Give her a few days.
- Warm but vague: maybe. One relaxed reply, then wait.
- Short and the conversation goes quiet: likely a soft no.
- She said it to a specific day you suggested: she may come back for that day, or suggest another.
- She’s said “I’ll let you know” before and never did: read the pattern, not the words.
Pushing for an answer versus leaving it with her
Each message adds pressure to a plan she hasn’t agreed to. She now has to give an answer on his timeline, which makes “no” the easier one.
He accepted her answer and stayed relaxed. She feels no pressure, and the conversation stays warm while she finds out.
What to send back
Why it works: Short and unbothered, it accepts her answer and leaves the next move with her without any pressure.
Why it works: One alternative, offered once, makes it easier for her to say yes if her only issue is the day.
Why it works: A little humor keeps the tone playful, so the plan feels like fun rather than an appointment.
Why it works: Changing the subject to something she cares about shows you’re not hanging on the answer.
What not to do
- Asking when she’ll know. It turns her answer into a deadline.
- Re-asking the next day or proposing a new date before she replies.
- Booking anything before she has said yes.
- Sounding disappointed (“oh okay… I guess”).
- Going cold to punish the maybe.
- Holding your weekend for her. Make your own plans.
How long to wait
Give it about a week. If she said she’d know “tomorrow” or “by the weekend”, you’ll usually hear by then. If the day passes and she hasn’t mentioned it, don’t send “so?” or “did you find out?”. You can keep chatting normally if the conversation is alive, but leave the plan alone. If she likes you, she has every reason to come back with an answer. If she never does, she has answered in her own way, and you haven’t spent your dignity asking twice. For the related “maybe” answer, see she said maybe to a date.
If she comes back with a different day
That’s a good sign. People who aren’t interested rarely suggest alternatives. Accept it quickly and make it specific: “Sunday works. Brunch at 11?” Don’t make her work to get the plan back on track. If she comes back saying she can’t make it after all, reply kindly and leave it with her: “No worries, tell me when you’re free.” If she then suggests nothing, see she’s busy and didn’t suggest another day.
When it’s really a no
A soft no feels unclear, but it usually looks like this: she doesn’t come back to the plan, the conversation cools, and she doesn’t ask you anything. That’s okay. Not every “I’ll let you know” is a decision she was ready to make. If you still talk occasionally, let her lead any future plans. If the conversation fades altogether, let it go. Pushing for a firm answer turns a gentle end into an awkward one.
Why staying relaxed helps
How you respond to uncertainty is part of what she’s judging. Calm, easy replies show you have a life and options of your own, and that you’re not anxious about one plan. That often makes a hesitant yes more likely. Pressure has the opposite effect: it gives her a reason to feel uncomfortable, and the simplest way to end the discomfort is to say no. Leaving it with her is not passive. It’s confident.
Let her invest in the plan
“I’ll let you know” is a moment where her investment decides what happens. Your role is to make saying yes easy, not to push. If she comes back, use momentum and lock in the details quickly. If you’re unsure how to ask again later, see how to ask her out over text.

What happens next
- She comes back with a yes: confirm the time and place.
- She suggests another day: accept and make it concrete.
- She says she can’t make it: reply kindly and let her suggest.
- A week of silence on the plan: treat it as a no for now.

What does it mean when she says “I’ll let you know”?
It can mean she’s genuinely unsure of her schedule, unsure about meeting, keeping options open, or giving a soft no. Her tone and whether she follows up tell you which.
How should I reply to “I’ll let you know”?
Lightly: “Sounds good, just shout when you know.” Then leave it with her and keep the conversation easy, without asking about the plan again.
Should I follow up if she doesn’t let me know?
No. If she hasn’t come back within about a week, treat it as a no for now. You can keep chatting, but let her raise any plans.
Is “I’ll let you know” a rejection?
Not always, but it can be a soft one. If it comes with warmth and a reason, it’s often genuine. If the conversation then goes quiet, it probably isn’t.
Can I suggest a different day?
Yes, once, at the time: “If Saturday doesn’t work, I’m around Sunday too.” Don’t keep adding options; one alternative is plenty and leaves the decision with her.
