Even if they give you there number it doesn't guarantee anything.
I have so many numbers from online dating, and I would say less then half actually meet up.
They are giving there number to a lot of other men also.
She thinks you're attractive, but I wouldn't take it personal. The other guys were more attractive and fun to talk and text with.
Which is why I always talk and have a conversation with any girl I am gaming. My success rates were close to 90% after I had a good conversation. texting? Maybe half if not less would meet up.
The call is important, but can also be a deal breaker if you come off weird. Asking interview questions, and talking about stupid sh*t like work, & boring crap no one cares about.
Ultimately though, it all falls down to your aesthetics. If the other guy is better looking, and is u per laid back and fun while chatting over the phone. She will probaly forget about you
A lady on Tinder offered me her phone number after exchanging just one or two messages on Tinder. If they find you attractive enough, there is never a bad time to ask for phone numbers short of the very first message.
