Don't text too much and try to get their number as fast as possible. Once they send you their number, don't open the message (many pages have an overview function), especially so during an 'interesting' conversation go on radio silence for a few days. Add her later and just don't comment on why you were not answering and immediately set up a date, by using voice message.
