He used to ask when you could meet, now he doesn't. What to say

Look at what changed. Did he stop asking about plans, or did his messages get shorter overall? A person who is busy will still ask when you can meet, just with less energy. A person who has cooled will stop initiating and only reply when you message first. Those two patterns look similar in the moment and mean different things.

Check the rhythm too. If you used to talk every day and now it's every other day, that's a real shift. If he still starts conversations but no longer sets dates, he may be interested in talking but not in the commitment of meeting. That's worth knowing before you decide how much weight to give it.

Also notice whether he's still sharing things about his life. Sending a photo of his lunch or a link he thought you'd like is different from answering in single words. Engagement in the small stuff often tells you more than the big question does.

The reply should do three things. First, it should acknowledge that the plan talk has dropped off, in neutral terms, so he knows you've noticed without you saying he's pulling away. Second, it should offer something concrete with a time window, because vague suggestions like 'we should hang out' are easy to ignore. Third, it should make saying no easy, so that a no doesn't cost him anything and he can give you an actual answer.

Keep the question open enough that he can pick a day, but specific enough that he has to respond to something real. Tie it to something you already talked about if you can. Avoid framing the message around what he's doing or not doing. Frame it around what you'd like to do.

Don't stack a second ask on top of the first. One clear plan with one clear window is enough. If he replies warmly, you don't need to say anything about the drop-off at all. Just make the plan and let the momentum come back on its own.

Send your message at a normal hour in the middle of his day, not at night when it reads as needy or like you're building a case. If he doesn't answer the plan within two or three days, don't follow up with another plan. One light check-in in a different tone, like sharing something you saw that made you think of him, is enough to keep the door open without chasing.

If a week goes by with no plan and only the occasional text, you have your answer for now. Don't keep filling the silence. Pull back a little, get on with your week, and see whether he comes back to it himself. If he does, good. If he doesn't, it's time to decide whether a relationship where you do all the planning is one you want.

Stopping is a valid choice here. You don't need to send a closing message unless you want to. Often the cleanest move is to stop initiating and let the thread end on its own.
