As a subscriber to Roosh's website, I get his frequent email updates, which are actually quite useful more often than not. Today's email I found especially interesting, so I thought I'd post it here:

I'm going to skip the whole moral argument that you shouldn't hit on a girl who has a boyfriend. I have the belief that if the boyfriend is doing a good job then the girl will be un-gameable, but each case is different and it's best to go with the flow.

For example, imagine you're making out with a girl in the club and then she says, "God I feel so guilty but I actually have, umm, a boyfriend." Should you stop and simply say goodbye? I say no because she might be unhappy with the boyfriend and looking for a replacement, but the bottom line is do what you feel most comfortable with.

Now don't even bother with NEWLY engaged or married girls. I think you'll have better chances with a nun than a girl who just made a fresh commitment with another man. It takes at least a few months for that moment to wear off.

That leaves two other types of girls with boyfriends: those who are unhappy and those who are neither unhappy nor quite ecstatic either. The best way to find out what type of girl you are dealing with is the length of time it takes until she drops the boyfriend in conversation.

The longer amount of time until she drops the bomb, the better. It's even better if she doesn't mention the boyfriend at all and you learn from a third party.

Now let's think about that for a second. If a girl is happy with her man he will keep popping up in her head, leading to a large amount of guilt when talking to a new guy she may be attracted to. She will attempt to relieve this guilt by mentioning him as much as possible in the conversation.

Therefore the sooner she mentions him and the more times she mentions him, the less likely you'll get anywhere. This fact should be your guide to see if you should commit to gaming a girl with a boyfriend, especially since they take more work than a single girl.

On the other hand if it takes a girl over 20 minutes to drop the boyfriend, consider her breakable. Now combine that with her engaging you, making eye contact, asking your questions, and touching you. The more she does any of these things, the less of an issue the boyfriend is and more you can proceed as you normally do.

It takes a little experience to tell between the girls who flirt just to feel attractive and girls who want to get banged by a new dick, but you'll know for sure when you go for the number or kiss. The former will put up Great Wall of China resistance and the later will only offer token resistance that you're already familiar with.

If the approach is going well and things are progressing past the thirty minute mark, just keep doing what you're doing and go for the kiss on the same night. When you get in close she will make a verbal objection, maybe mentioning the boyfriend, but just like you would do if she was resisting in the bedroom, simply agree with her so she doesn't think about it further.

Don't make it a tug of war, but definitely try again a few minutes later as an attempt to break down the resistance. If she says she can't do anything with you just smile and say you weren't trying to do anything with her anyway. But keep pushing until you get it.

For girls that seem to be breakable but not easy, the only way to do it is through regular access. If you work with her or see her weekly, then these repeated encounters will nibble at her resistance until she just goes through with it. But if you meet her one night in the club and just get her number before saying goodbye then the seduction is over because she won't allow herself to see you again without feeling like a cheat.

Look, if a girl puts herself in a position to cheat, she will cheat, and you'd be foolish to pass on it for some other guy to smash it. I found this all out the hard way years ago when I believed the best way to get a girl with a boyfriend was to first be her "friend." I fondly remember all those wasted nights talking with these girls on the phone about the problems she was going through, with no bang to show for it in the end. It was an embarrassing period of my life but I think about it every now and then so I don't get complacent with my game today.

It wasn't until my first success with an engaged girl at work that I learned how having access is critical to getting with desirable girls who were already taken. If your game is tight, she will eventually make it all too easy for things to progress.

But before I was banging girls with boyfriends, I first learned how to pick up single girls in bars, clubs, coffee shops, and the street, after hundreds and hundreds of approaches. The result of all this experience is my book Bang, which features a reliable system that is flexible enough for you to inject your own style so you don't turn into a "social robot."
