How to reply when she says "we'll see"
Verdict first
"We'll see" isn't a no. It's "impress me" — or "if nothing better comes up". Your job is to make the plan so easy and specific that saying yes is the path of least resistance.
Translation from her to plain English
Usually one of two things: your invite was too vague to say yes to, or you're not a priority yet. Both are fixable — but not by asking again in the same words.
Make it concrete
Swap "sometime" for a day, a time and a place. Give her an easy out so the yes feels free:
Fair. Thursday, 7pm, drinks near your place — I'll keep it short
"We'll see" is basically a yes. Thursday night. What time works?
All good. When your week calms down, you know where to find me
If she dodges again
Send the third line above and go quiet. Interested women come back with a day. Chasing a second "maybe" only lowers your value.
