Boyfriend & Girlfriend sets. How?

I mean.. where's the context here. Have you tried before and have some experiences to share? Otherwise you just sound like a kj faggot trying to mentally masturbate. Yes I've banged tons of chicks with boyfriends, husbands, took her off a date, competed with other guys yada yada, but if you're just asking just to ask when you're really just a newb who should be simply concentrating on "talking to girls" I'm going to laugh. 

I thought i'd get linked to a good article or video and didn't want to write half a page of ''TL;DR'', but here are my experiences:

At first i did what my wing would do and ask ''are you two dating?''

If they said Yes, i'd just say ''Okey, have a nice day'' and leave, if No, i just see it as a mixed set. (The guys very often walk away, Norway :p)

Later i tried a more bold approach where i just start gaming the girl (after asking) and ignore the boyfriend or engage him a little.

This usually resulted in the girl becoming defensive or leaving once i start showing intent. The boyfriends don't really do anything about it. Most they have done is just take the girl with them and leave.

My thoughts: Stop showing intent, but then i thought... game = woo + intent., so that wouldn't make sense.

Then i decided to stop doing those sets, because it's ''unethical'' or whatever excuse i gave myself not to learn it.

Today i saw a personal 9 walk with a fucking peasant wearing a dcshoes baggy hoodie in 2014 and i knew that if he wasn't there, she would be mine, but he was there and i don't know what to do, to not trigger that emotion in her which tells her to react the way they usually react. (see above)

What i want to know is how to make sure she won't feel threatened or whatever and jump into her comfortzone by asking me to leave cuz ''shes there with her boyfriend'', but at the same time show intent.

On Friday when i meet my wings we're gonna try to open those sets in pairs and see if distracting the boyfriend will work. 

PS. I am not asking what to do if she is alone and tells me she has a boyfriend, i got no problem with that. It's only when the boyfriend is actually STANDING next to her.

How many girls have you banged this month spaghetti?

As many as you have +1. 

It's a very serious question mang. A dude getting laid regularly just isn't thinking about stealing girls off their boyfriends. It's also pretty unhealthy. A dude who actively goes after girls with boyfriends will never get very far in society.

But your huge GLARING mistake is that you ask if they're dating. Fucking terrible

Are you talking from experience, cuz your first post in this thread implies you do.
