Search Results: buying a girl drinks

So basically i went out with my friend (lets call her amber) to a bar about two weeks ago. Initially it was meant to be a girls night but then we thought it would be fun to get guys to buy us drinks.(our reasoning being if they are so entitled tht they think that buying us a drink means we will get with them means they deserve to buy us a drink and we dont owe them anything) so a couple of guys are buying us a some drinks and then they introduce us to some more of their friends. Their friends then get us in to the club next to the pub for free (and we get to skip the line) we dance for a bit and then Ambrr goes off with one of the guys for a fag outside and i am left talking to a few of the guys by the bar in the club. A guy at the bar asks me what im drinking and then buys me a bailey, telling me he saw me across the pub earlier. We had a quick snog and then i walked away. Not long after i saw amber again and we started dancing again. Then she went off for another fag and i got bought another baileys by another hipster guy. We also had a few swift kisses.
Basically i was very drunk and kind of cheated of my boyfriend of 3 months. Should i tell him? I dont want to break up and as the kisses literally meant nothing (i can't even remember the guys names) is it worth hurting him by telling him? What can be achieved?
Amber didn't see, and i didn't know anyone in the club, so unless i tell him he will never find out.
