This actually happened about a year and a half ago now but to this day it still plays on my mind. By the way long story coming up, sorry :\. Anyway basically I was with this girl for about 6 months, when she starts making remarks about one of my best friends. For the sake of argument let's call her L and him S. Essentially L starting remarking about how sexy S was and how her and her friends always talk about him. I thought nothing about it. Then one day she randomly asks me what I think of cheating in the relationship. Caught a bit off guard I am honest and say it's despicable and should never be done as if you want someone else that much you shouldn't be in that relationship. She then randomly gets in a mood with me for the rest of the evening, again I think nothing of it. After 7 months she leaves out of the blue me without giving any real reason and a week later is with S. Now my question is, was she cheating on me? I don't really mind if she was, I have been with my current girlfriend over a year now and am very happy, but I burnt bridges with both of them over it and because of which it still haunts me whether I could have cut two very special people out of my life over nothing :\
