YES.

Sometimes even before you've talked, and often before you've realised it.

You sound like you know the risks, is it possible to meet before things get way out of hand ????
At the risk if sounding cynical - I'm sure it's easier for someone to be less than honest by email/phone/text, no body language or facial expressions to give additional info.

On the other hand - maybe a 'long-distance' relationship would suit you.

Good luck :)
