A woman made first contact via a dating site !

She works as a nurse (I think - her profile doesn't say her job but the messages indicate that's what she does), is in a similar situation to me family-wise (mature age with a young child - her's is 5 yo), and we've just swapped phone numbers two days ago after a bit of online chat for a week.

Not spoken with voices yet because of our schedules not lining up with free time. Hoping to take that step in next day or two.

How long is too long to wait before suspecting the person is not legit when there's been a delay in a contact reply? I sent a txt message this morning, and one yesterday, just saying 'hello and good morning hope you have a lovely day' sort of thing and no replies.

Should I just take a punt and call to see what happens?
