OK so I've just found out my mother isn't in love with my step father anymore they been together 20 years married 17, she's been messaging this guy who she says she really likes and gets butterfly's all the time, she's lying to my father because she's going to stay down that guys house soon, should I be OK or not, I don't know how to feel or what to say, she's talking to me like I'm OK with it and I know it's not gonna be nice on my father's part because he is in the dark, but surely she can't do this and not think about the consequences. In time it's gonna come back and bite her in the tail :(
