Giving out her number concern..

I'd leave her on read and re-engage in a few days. She's only half-joking about the stalker stuff - the best way to solve that is to move along and show you're not obsessive

My copy paste answer to that objection is "I don't use snap anymore. If you end up hating me you can always block my number", but it properbly wouldnt work on her since she seems pretty set on not giving numbers. Sometimes I just take the snap and its a 50/50 if your are going to get lost in the sauce

"Too lazy to stalk ;). Rather just have you come over instead. You'll have my real number too. Don't worry"
