Strange enough this seems to be an occuring theme for the past week.
Here's a little background info: Just out of a long term relationship, Because of that I got into the game, Not much experience, However I still seem to be okay to pick up women (it's afc-style, just not to my full quality and quanity levels, thats what game is for now

) Both girls listed below are 7's by my standards. Anyways, Since my LTR break up, two of this girls have talked to me quite a bit through facebook, texting blah blah. I've had sexual interaction with both of them in the past, years ago.
Girl 1: I'm certain that she's into me, initiates conversation first occassionally, sometimes seems a bit stand-off-ish but it's rare. We have a decent past to work off of, we were both pretty into eachother back in highschool, then she moved to a nearby town and things tapered off before an actual long term happened. Sent a picture message today without a shirt on in a way to "qualify" herself in a conversation that she still looked good. Funny thing is I didnt' even ask for it, it came at random. This is how I'm certain she's into this. Has an on/off boyfriend that she has issues with. Got into a conversation today about how she doesn't know why she still hangs out with him he ignores her, blah blah, How me and her need to set up a date, etc.
Girl 2: More recent past than girl 1, Has a legitimate boyfriend who seem like they have a good relationship. Got into a bit of conversation the otherday as to how we should of jumped into things before she got the boyfriend (IOI I take it or she wouldn't of bothered mentioning) Talked a little bit about the sexual part. However, she can be untalkative at times with the "one word reply" bullshit girls do. I'm not sure how to combat that yet.
Anyways, Being busy with finals this week I haven't been out to any partys or anything, these girls haven't required much work they've just fallen in front of me due prior involvement so it's the best way to solve a busy week without much time for actual social interaction. The thing is it's not going to bother me to screw things up with either one of these girls. I don't have any oneitis attachment, but both are fairly physically attractive and I wouldn't mind boosting up my confidence by having sex with either one of them.
What can I do to deal with this touchy subject of boyfriends? I've definitely been avoiding the subject as a whole in conversation, But it's apparent "girl 1" wants to complain about her shitty relationship. I don't think it's a good thing to put myself in that position, as it can lead to LJBFs (Although with a sexual history maybe unlikely?) Either way, Anyone have a good plan of attack as to dealing with a situation such as mine?
