There is a certain kind of girl out there and she is not a Hot Chick. You probably have a friend or two like her. She does some stuff now and then that you don't necessarily approve of, but it's not that bad, so you don't give her too much crap about it. She probably cheated on her boyfriend once or twice. Yeah, she was drunk - like, really drunk, but it's been a problem in a lot of her relationships. She also used to date girls in college, and once in a while (like when she's really, really drunk) she'll still make out with girls in bars. This has been a problem in a couple of her relationships, too.
Well, anyway, now she's getting married! They haven't known each other long, so it's a little shocking, but you're happy for her. He seems like a pretty stand-up guy, and you hope she doesn't do anything too bad to him. The weird thing is, she is thinking about inviting her ex-boyfriends to her wedding - not only the ones she's friends with, but even the ex's that she cheated on and hasn't spoken to since. She claims that the invitation is a final olive branch that she wants to extend to these men who were an important part of her life, but you still think it's a little bit inappropriate.
Well, we know lots of girls like this and they totally suck. Think about it - what do all 3 of these behaviors have in common? They are desperate, pathetic ploys for male attention. Yeah, there are lots of reasons to cheat, but consistent drunk cheating is usually for no good reason and the specific no good reason in this case is usually a desire for attention - "I'm so sexy, and everyone wants to make out with me! I can prove it!" As for making out with girls, we're pretty sure bisexuality exists, but chicks who get drunk and kiss other girls in bars in order to turn men on aren't bi - they're attention whores. We find that they're so often the exact same whores who are inviting their ex-boyfriends to their wedding, and funny enough, for the exact same reason.
It is a very special kind of women who wants to be surrounded on her wedding day by penises that she is intimately familiar with. Why would any woman want that? We're not saying that you should pretend to be a virgin at your wedding, but it's also not quite the right time to show off your previous conquests. It might not be ideal for you fiancé to look at you in your white dress and right over your shoulder at the last guy you boned before him. It's not really romantic, and it's totally not cool.
So if you have a friend who's doing any of these things, for the good of sisterhood everywhere, tell her to stop. Let her know how cruel it is to cheat, how her poor unsuspecting boyfriend will be scarred for life by her actions. Then tell her how pathetic and lame she looks when she gets drunk and flirts with girls, and that it totally is cheating when she goes on to make out with them in public. And most importantly, if you are a bridesmaid or a maid of honor in a wedding where the bride's ex is supposed to show, you have to stop her. Weddings make people a little nuts, so assume that she doesn't realize how ridiculous she's being. Delete her ex's number from her phone before she can drunkenly text him, "Is it cool if I invite you to the wedding?" or go to the calligrapher's house and sabotage his invitation if you must. Help us show these women how stupid they're being, so that we don't have to show up hand-in-hand with the bride's ex at a wedding ever again.
