I was talking to a woman very recently and I asked for her phone number. She said "why don't you give me yours instead?" She put it into her phone as we joked about me having difficulty remembering my own number (I never call myself)
That's a polite rejection, isn't it?
Did you just walk up to this chick and ask her? Is it a first time day interaction? (As in you've never spoken to her before?) If this was a first time interaction and you've never spoken before, most chicks operate off the "creepy/desperate dude" factor if they don't know you from a can of paint no matter what some "DJ" would otherwise like you to believe UNLESS she finds you hot as fvck FIRST. Meaning your look, swag/game being charming etc. (I've seen several even good looking dudes get blown out like that right in front of me. They come off as desperate or too "amped" up like a potential rapist to get the chicks number and get blown out with the BF line etc.)
Either way you never ask for a woman's phone number. You pull out your phone after talking to them a bit and tell them to put their phone number in and you'll text them yours in a few and will hit them up sometime to BS. (You can't just come off like you want their number to date them right off the bat unless they are REALLY into you, in which case they'll most of the time offer theirs without you asking.)
You have to slowly build a chicks trust (when you meet for the first time) IF you aren't an adonis in her eyes by BSing, keeping things light hearted and having her engaged in your conversation as in asking you questions and seeming enthusiastic about the interaction. (NOT in an "Oh I need your number so we can date A.S.A.P.) Again, chicks IF they do not find you an adonis right off the bat will blow you off. In time they might warm up though. In the meantime hit up many more chicks and don't wait around.
You end the conversation/interaction after talking a bit, pull out your phone and HAND IT TO HER and TELL her to put her number in your phone and you'll text her yours in a few to BS later.
If she refuses you tell her: That's cool. (Change the subject and chat for about half a minute more about something in your surroundings instead of just walking right away to avoid looking bvtthurt. Some chicks want to see how you react if they don't give you their phone number and when they then see you don't care, don't immediately run off pouting after you didn't get what they then think you REALLY wanted by talking to them will offer theirs up. Semi-sht test. IF she then gives it to you text her yours on the spot and talk to her later.) IF NOT: SMILE and don't change your demeanor from the positive person you were before she said "no". Keep that SMILING poker face. Then tell her: "Well it was nice meeting you. Take care. See you around." And then walk off.
If she tells you to give her yours instead you tell her: Ladies first. You give me yours and I'll text you mine right in front of you this way I give you the right number.
