Now, I have another problem though. X3 This one concerns me a little less, and is more of a general question.
What is the "rule" per say about dating someone who is a friend's ex, or whom your friend likes?
You see, this question was raised in my mind because of a recent situation.
It involves three people, whom I will call Snapple(M), Peach(F), and Bubbles(F). (Sort of an inside joke thing)
Okay so Peach and Snapple were dating. I never got the full story, but basically, a few months ago Snapple broke up with Peach, and I was informed liked someone else- unknown who though.
Well Bubbles is a girl who really likes Snapple, but is friends with Peach.
Recently, I felt like Snapple might be flirting with me. (and I'm actually generally a bit oblivious to that)
Like seriously I don't even know how flirting works.
This is me:

He'd do very excessively teasing type things, and we would get into little fun petty contests.
Example: Today we had water balloons, and we would continuously get payback on each other. He'd hit me with water balloon, I'd target him. And long after the game had ended we were still sneaking up behind eachother and splashing the other with cups of water.
But I'm honestly not sure if he's flirting with me, or with Peach. Because we would somehow both get into these contests against him. And also, he'd be the guy who would probably not ask to get back together because of his pride.
Example two: He called the two of us over to play soccer. Well, he played 'no blood no foul' so a lot of pushing, shoving, and the sort. But he seemed to be a lot more physical with me- picking me up, rolling around a bit, grabbing and lifting up my leg to make me trip a lot, etc. But I don't know if that really means anything, because Peach is also a lot smaller, and .... frail I guess? Definitely more girly- whereas I have 5 brothers and Snapple would know I could take anything he gave me.
So I don't really know.
So I sort of went over the idea of him liking me, and I thought about it. To be honest I don't actually know if I like him or not, or if he likes me.
But I think even if we both did, I might not go for it, just because it would be a lot of drama between Peach, Bubble, and myself.
I mean, on one hand, I don't think you should give up a chance to be with someone you like because of a friend- if their really a friend, they should look past it, right?
But at the same time, I don't know if being with Snapple (someone I'm not even sure I like) is worth losing two friends.
So, this just put me in a mindset where I was curious to know, in general, whats the rule or protocol for going out with guys who have some sort of drama with your friends- in particular, exes, and current crushing.
