Listen, chickadee, you are way beyond hurt feelings. If a guy did this to you, you would be calling your best friend in tears. Just because he is a guy doesn't mean he isn't a human being with real emotions. And for that matter, who do you think you are? Zack Morris? It's been done on Saved by the Bell, my friend, and it will eventually come crashing down around you. When you date a guy for a significant amount of time, especially if they are all emotional as you have described above, it is safe to assume that he is taking things WAY more seriously than you are, and considers the two of you to be practically engaged. This considered, you will break his innocent heart to pieces when he finds out via the rumor mill that you are seeing not just one other guy, but numerous others. You should let them know that you are not exclusively dating, and that there are 2,3,4 other guys you are seeing. This may not go over so well, but total honesty is key in these situations. Then again, maybe if these are open minded guys you are dating, they would be up for a good old fashioned "the more the merrier" roll in the hay. Then everybody wins! It's worth a shot. Or perhaps you could delegate specific date nights for each clueless tool you are seeing ("Jack, you can have me on Friday, Otis, on Saturday...") and everybody gets a piece. Just keep telling yourself, 'I'm not a slut,' and no matter what, play on, player.
