So, like I stated in one of my comments, while I think there might be problems with this type of friendship, the truth is I think it's pretty hard to stop ourselves from hooking up, and now I got proof of it.
Right now, I just got home from her appartment, in which she had a small gathering of friends. I had gone in my car, so I wasn't drinking, and I could leave whenever I wished. After everyone left only my friend, her roommate and me were still there, so I just told her I'd leave. My friend went like: "I'll walk you down", and I went like "sure, thanks" (Right now I don't think it was too subtle, who the hell walks someone to the parking lot lol).
Once downstairs, all sorts of things started happening. As soon as we were out of sight of prying eyes we got together. It was nice, fun, and pretty... spontaneous, and extremely exciting.
Apparently she's been thinking about this too, and apparently, we've both agreed to carry on with it, with the "perks" it involves. I'm not sure what I'm doing here it's just extremely impulsive, and while it scares me a bit, it's also awesome.
I don't think I can stop it at this point, so I might as well enjoy it... right?
