Treating each other with respect during the 1-2 hours you are with them and letting yourself experience the "fantasy" is a big difference from getting emotionally attached to someone, in or out of the hobby. Not saying there is a right or wrong here but remember that in most cases this is the lady's main or only source of income. The match.com post may sound flippant but in probably 95% of the cases, the emotional attachment you feel towards the lady is her manipulating you for more money and repeated business. There are, of course, exceptions to every rule and Grizzley may very well find one or has. Three cheers for him if that is the case.Cryptkicker breaks it down very nicely. I would add that a good provider, who provides a real GFE, may leave a man feeling like she is a girl friend.
Now don't mistake this statement with whether you can have friends in the hobby, male and female. You certainly can and I do. But the friendship part is free. The business part is business.

Don't allow yourself to forget this is a hobby for the men, and a business for the women. If you allow yourself to become emotionally attached to the women you pay to spend time with you then you are probably going to spend a lot of time feeling butt hurt and betrayed.
Be friendly, courteous, respectful, and treat a lady like a lady. Have fun. But do not allow yourself to forget it's a fantasy.
