i'm dating a girl, is nothing serious because she is a student in my city and she will leave the country for good in two months.
i really like her friend and i'd like to do something, i'm not the type of guy who fuck my girlfriend's friends because i think is disrispectful but in this case this isn't a serious relationship.
i just spoke to this other girl a couple of time and i never have the opportunity to speack longher, i was thinking of adding her on facebook.
it's risky and dangerous, i know but i think is the only way.
what do you guys think about ?
should i add her ? how can i hyde this ? like if i have an excuse for adding her will be better so the girl that i'm dating won't be suspicious.

another situation is of another girl that is leaving the country in two months too, i dated her a couple of time and than she told me that we can't date anymore because she start again with her ex boyfriend back home.
there is a friend of her on facebook that i really like but in this case i never met this girl before.
i was thinking of adding her and try
what do you guys suggest ?

never keep secrets thats where you step over the line of being a PUA and a rotten player. be upfront and say what you want me personally i would never get with my Gf's friends because its a dirty thing to do, theres more women in this world then men so dont just be looking in ur girlfriends back yard... and with the facebook thing its worse then texting in my opinion, never do it man up get her number call her.

i think you misunderstood me.
first is a girl that i'm dating and she also have a boyfriend, second i would ask for number if i had a chance but i don't have that's why i was thinking about facebook
