Glad to hear that you are thinking about what your son needs. He does need his father in his life and I can understand the frustration you have with your H. However, your son can't be punished for your H actions.
As far as the rings go I think the thing that hit me the most is her conviction to sell them. Based on all the reading I have done most people regret their affairs and the damage they caused their family. Her actions to sell the rings makes me feel like she doesn't regret what she has done or is doing. It also makes me feel like if she did regret it in the future she wouldn't say anything since she already disposed of the two things that symbolized our R/M.
I am doing better with it today. It is her choice to do what she wants. It is my choice to continue moving forward focusing on myself and my boys.
