I'm not sure what booking a hotel has to do with your girlfriend, but here is a suggestion. Find a new girlfriend and go slowly in the relationship until you know her and she knows you. Hold off on sex for two reasons: so you avoid contracting a sexually transmitted disease from a virtual stranger and because sex right away with someone new only makes it more difficult to form a lasting relationship. Any woman who gives you stories about having feelings for other men should be cut loose to go have feelings (and whatever else) with those men.
