Hi BiddyBrown: I'm glad you worked thing out with your husband, but I'm sorry about the situation with your mom. Did she purchase property that adjoins yours?
You don't have any control over your mom's behavior. The only thing you have control over is yourself and the way you interact with your mom and the way you react to her. Have you set
BOUNDARIES with your mom? Boundaries are for your benefit and are up to you to consistently enforce.
AVOIDING CIRCULAR ARGUMENTS is a good strategy to follow.
THE KARPMAN DRAMA TRIANGLE workshop can help you learn about healthy triangles, versus unhealthy ones. Avoiding arguments and not reacting with emotions, can be a beneficial strategy on your part.
Sounds like there are some drama triangles going on with your mom and your children. Does your mom interact differently with your children, as opposed to you? Sounds like you son lives elsewhere. Is there a reason he goes to see his grandma every day? If you removed your mom from the equation, how have your children reacted to your marital problems?
I'm thinking that once you move, it should be easier for you. Once you leave the situation of viewing your children go back and forth to visit your mom, it should be easier for you to process your emotions.
