To start off, 2 days ago i went over to my closest friends house, we were there for a few hours then his girlfriend came over, apparently he and she have been having problems for some time, and long story short, girlfriend makes advances towards me and i reciprocate, the entire time going "oh [censored] this is trouble' and yet i kept going. so i leave my friends house very very early morning, and his girlfriend who will now be referred to simply as woman, asks for a ride home, halfway there she asks me to pull over, and basically spills her heart to me, mind you we had only met that night, but she felt a very deep connection to me and i to her, yes i know what your thinking but no im not some testosterone driven teenager, im a testosterone driven 20 year old =P
Continuing the story, after our long talk, we decided to go for it and from a relationship, and well, went a bit quicker than i ever have on a first date if you know what i mean, skip ahead to today, me and woman meet up again, talk, have fun, and ruffle the sack so to speak, again mind you, she wanted to talk to my friend about their relationship but was not able to up to this point, so i kind of feel like a bastard for doing this without talking to him first. After we have another talk where she tells me she still loves my best friend, but just cant see herself romantic with him anymore, but apparently is a tad bit insane about me 0_o..so moving on she calls me after i take her home, informed me she talked to best friend, and now she wants to date us both at the same time, yet has not told best friend what happened between us but it was implied that he knows what is going on.
now you may be asking yourself at this point "who the hell are you,and why are you wearing my underpants on your head", to answer your question, because i feel like a superhero..but that is besides the point i suppose, i honestly do not know if i should even talk to my friend about this, what to say to him if i do, and if i should even continue this relationship (which i really want to do as woman is basically everything i am looking for)
what advice would the wise, nerdy, and slightly unhygienic community have to offer this confused man?
