She posted her phone number right on her profile? Very fishy. Consider possibly that she's fishing for clients.... maybe. Or something else strange is going on. But who knows... maybe she's legit too. Go for it and see what happens.
Is this the same girl who left her phone number on her profile and wants to be paid for sex? She may have ditched you when she figured at the end of the date you wanted to seduce her, and not pay her...
