I've had it!! Enough is enough

Re: I’ve had it!! Enough is enough

Let’s assume that FIL’s intention is to cause a rift between OP and her husband …he’s succeeding in stressing her out …and that stress is seeping into her marriage, so it’s working isn’t it? She’ll have to react in a way opposite to FIL’s expectations and that will require will power. So, if he expects her to get defensive, angry, and to challenge him…then she’ll have to behave in the opposite manner (unperturbed, calm, etc)

Maybe FIL was smiling because he was amused at their bickering…in that he found it silly…or perhaps he was reminded of the conflicts in the early stages of his own marriage.
