I'm really struggling with this and could do with some impartial advice.
There's a long history but here are the essentials....
Have known DH for 17 years - MIL was unhappy about our marriage and made it clear that I was not "good enough" for him. She is an alcoholic, and regularly rings up when drunk, leaving abusive messages. She alienates most people in her life - had no relationship with her own mother, her only brother will have nothing to do with her as she is so manipulative/unpleasant.
My DH dislikes her and tries to keep contact to a mimimum, but she is always writing letters or on the phone to him. She is single and basically seems to rely upon him in the same way that you would a spouse. I cannot understand why he continues to have any contact with her but I suppose that he turns a blind eye to her bad behaviour because he was conditioned to accept it.
I want to be supportive of DH because I do not wish to make a difficult situation impossible for him, but I am finding it increasingly hard to tolerate her in my life.
I don't wish to give DH any sort of ultimatum, but just recognise that I am unhappy having this toxic woman in my life.
If anyone else has a similar situation, how to you cope on a long term basis?
