Well, my partner has just told me she cheated on me last week. Didn't 'go far', but still.
I'm annoyed at my initial laid back reaction, we've all made mistakes. But I've had a shower since and thought about it, I thought "has she just told me cause Derek (best mate) seen her?"
I did the typical "is it me?" s***, now I just want to boss her head off a wall. My initial reaction has just allowed her to settle down, when I'm getting more and more enraged every minute.
