So i have somewhat of a messed-up story... It's kind of confusing, but i'll try to simplify it as much as i can.
The people involved are Me, my sister, the girl i'm seeing (who's also my sister's "best" friend), the guy my sister is seeing (who's also a really close friend of the girl i'm seeing), and the girl i'm seeing's gay best friend (who's also the brother of the guy my sister is seeing). I just realised, saying it like that already makes this sound very redneck. To make things easy i'll just refer to the girl i'm seeing as A, the guy my sister is seeing as B, and the gay brother/best friend as C.
So my sister introduced me to A a few weeks back. We hit it off immediately. Went on a date a few days later. Pretty much followed the generic path most people do during the "development phase" of a new relationship. After about 3 weeks we both came to an "agreement" that we wanted to be exclusive. Up until now i thought things were pretty normal, following a normal path. Obviously this is when the twist came. I was on my way to go see A one night when i got a phone call from my sister. She told me the following:
B and C apparently had a conversation in which my "relationship" with A was brought up. C told B that A was only using me to get back at my sister. Get back at her for what? Well A and B were really close friends, but once my sister and B started showing interest in each other, A and B no longer hung out as much as they used to. To simplify it, A was mad that B was starting to spend more time with my sister than with her (A). She(A) felt as if my sister had "stolen" B from her, so she(A) was angry at my sister. So in her(A) mind, the best way to get back at my sister was to sleep with me. I know, i know... this makes no sense. Anyway.... the reason B knew this was because C had told him so after A had told him © so.
At the time it didn't really bother me too much because i really wasn't looking for a serious relationship anyway. To me A was not much more than just someone to hang out with and hook up with. But now... i feel like things are different. A is changing her behavior towards me. Starting to become slightly more serious. Our conversations are becoming a bit more meaningful, were starting to do things "normal" couples do, etc. And truth be told, it's confusing me ever so slightly.
Now when me and my sister spoke about this a few days ago she told me that A has been talking to her about me a lot. The way she's starting to feel about me, etc. Keep in mind that no one (except my sister) knows that i know everything. So A doesn't know that i'm aware of what she said/did. And truth be told, it's confusing me because a.) either A is playing the long game (the VERY long game), or b.) she's actually starting (or already started) seeing potential in our relationship.
I'm still not sure how i feel about the whole situation. On the one hand i don't really want to ruin a good thing. What we have is good. We have fun, a lot of fun. And i feel like i have the ability to control my emotions (as in completely keep emotions out of it) for now. When i spoke to my sister about this the other day she said that perhaps A's initial intentions were just to sleep with me, "get back at my sister" and then "dump" me, but now that we've gotten to spend more time together she's changed her mind. So the confusing part about all of this is that i'm not sure what to do. I feel like i should confront A about this, but i don't really want to deal with all the drama that comes with it (because it'll most likely create drama between my sister and B, A and B, B and C, and so on and so forth). But additionally i don't want to get bamboozled and end up being a centerpiece of A's long-game (assuming her feeling have not changed the way i think they have). It's only been a few weeks, so it's still very early to judge, but me and A are very compatible and i know that we can very easily have a very long term relationship.
So yeah... this is fun...
