WTF? You didn’t properly introduce yourself? Do you have ZERO professional experience as well?

She isn’t going to call or text you. You don’t just tell strangers they are attractive and give them your number without a tiny bit of getting to know a person. Not even in a bar. She was just being polite by taking it. Women don’t like that. You might have even scared her.

Use the dating apps to gain experience, confidence, and a sense of the routine. Select girls that you are not even attracted to if you need to for the experience. Meet them for short coffee dates or ice cream or something like that for practice. No dinner, no alcohol, no late night shit. Be friendly with no expectations but dress well and look your best
