I don't know if it's a SIGN but PLEASE don't meet him alone.
I would bring a friend for security AND to see if the guy is a creep. AND I would meet in a public place.
Brittany, if you have a bad feeling about this though...don't do it! You don't owe anyone anything....do what you feel comfortable and happy about doing!
I know you'll do the right thing for you...but we're here if you need us!!!! *big big hugs*
