My soon to be MiL is a very selfish person when it comes to my F. We haven't told her that we are getting married yet bc when we do we know how she is going to react. To my face she is going to act like she is happy as a clam but behind my back she is going to go on about how I am taking her son away. To be completely honest she gets on my nerves quite a bit. She is 66 going on 3.
On to the real problem...
She has been married at least 5 times and I don't want to wear one of her engagement rings. If she offers it I will have to refuse and that's where the problem is. My eye teeth doesn't see the bluntness coming and I know I will hurt her feelings. Then she will run and tell everyone how mean I was to her and that I don't appreciate anything. Can someone give me an idea on how to politely refuse the rings? What about how to deal with the back stabbing?
