What to say when she says "yeah maybe I'll think about it"

Look at the invite you sent before you look at her reply. A plan with a day, a time, a place and an easy way to say yes gets a clearer answer than a loose "we should hang out." If you suggested something she has to make room for, with no real detail, then maybe is often her way of saying she needs more information or doesn't see a fit yet. If the invite was specific and she still said maybe, that is more likely a real hesitation about you, the timing or the setting.

Her tone matters too. A maybe with a question mark or a light emoji reads as open. A flat maybe with no follow-up question reads as closed. Check how much she was engaging with you before the invite. If she was asking questions and sending messages that were longer than yours, the maybe is probably a logistics pause. If she was already giving short answers, take the maybe as the answer it is.

The most useful thing you can do is remove the friction. If she is unsure about the plan, offer a smaller version or a different day, and make it clear that either choice is fine. That gives her a real decision to make instead of a vague one she keeps putting off. Keep the new option concrete, with a single time or place, so she can say yes or no in one message.

The other job of your reply is to let her off the hook without making it awkward. A light line that shows you heard her and are not offended lowers the stakes. It tells her she can come back later without any cost. People often say maybe because they don't want to disappoint you, so making a no feel acceptable is what gets you a straight answer.

Give her a reasonable window before you follow up. For most people that means one to three days, longer if you are not in a rush and she is still active elsewhere in the chat. Sending a second message within a few hours turns her maybe into pressure, and it tells her the decision is now yours to manage. If she has not answered after a few days, send one short, friendly check-in that mentions the plan lightly and gives her an easy out, something like a question about whether another day works. Keep it to one message.

If that gets no reply, stop. Silence after a maybe is an answer, and continuing to push is the fastest way to lose any remaining goodwill. Do not send a guilt message, do not comment on her social posts as a substitute, and do not send a longer message explaining why you think she should say yes. If she comes back later with interest, respond warmly. If she doesn't, let the thread end without a final message asking why.
