If you suspect there is an affair, you're better off not saying anything until you have proof. If there is an affair (or one is developing), all you will do is show them they have to be more careful in hiding it.

Once you have definite proof, then you lay down the law.

If he's just telling tales or getting advice, then don't worry about it.

I don't think it is an affair. But I do think she is running and telling him everything I say or do. She is either against me or trying to help me. I just don't know.

I can't trust my sister. Wow.
