Re: Mother in law’s boyfriend
No, one should not be oblivious to it and by noticing and forming an opinion on it, the OP has already made it obvious that she is not. However, one should not aggravate the situation either. Realistically, what will the OP’s involvement actually accomplish? Given that her mil, knowing what she is risking by behaving this way, continues to see her gentleman friend, it’s rather unlikely that the OP’s involvement will change this.
Also, if her mil doesn’t care what her husband and children (and God for that matter) think of her actions (and her brazen, nonchalant behaviour indicate that she doesn’t), why would she care what the OP thinks? If the OP confronts her mil or gets involved in any way, it will only serve to antagonise her mil, which will lead to further discord in the family. Again, the best course of action would be to move out and keep her distance from this situation until it is resolved.
