I know lots of bros here should have experience in this, which is why I want some advice.

Happened a few times where wls give me their numbers/we chats
We usually text really happily and flirty for the first few days, then it starts to get cold really quick, takes long to reply and single word replies.

Flirting stuff usually including sexting, and random questions on what were doing right now.

So I'm just wondering how do you usually text wls? And what signs in texting means she wants to go on a date or just want a customer relationship?
