God this is turning into a gangbang!!... stop frothing at the mouth and put your peckers away boys! she's not a piece of meat! lol

If like you said the guy last night was negging you and you didn't like this, why didn't you call him out on it?? Simply say 'Are you negging me?' if he pleads ignorance to this then you can explain what 'negging' is. Expose him if you have to, grab him by his balls. Demonstrate that you know his game and that you can play this game to.

Most women know how to play men, and most men are oblivious to being played or don't know how to play back. Sometimes when a women meets a guy who won't be played, and he knows her game, can play her at her own game and is a match for her she is more likely to respect him and feel attracted toward this guy. Reverse those roles.

Sometimes guys lose respect for women if they are too easy to be played, alot of men like the thrill of the chase, the harder they are to conquer the greater the taste of victory. This is just human nature we see less value in things which are easy to come by and place more value into things that require more effort to gain a reward or are scarce. Remember 'cat-string theory' right?? the same doesn't just apply to women it applies to men also.

It sounds like this guy has the upper-hand here, and you've given most of your power to him. Wrestle it back if you want but the best course of action really would be to just move on. Next time you're out with him, flirt with random guys and turn up the heat with these random guys, then see how this guy reacts to being strung along.
