It was over 20 years ago, but the pain has resurfaced again now because I have started seeing her Facebook posts about how great her life is. I feel so angry. How can I handle this?
First thing that you must realize is that most people only post the "best parts" of their lives on Facebook, some people even go so far as to make their lives seem better or more interesting and post mostly false views of their life. Facebook is watered down, candied version of our life, you put on there only what you want people to see. The questions you should ask is "How have I grown from this?", Is my marriage currently in a good place? I really wish there was some form of magic that could be performed to solve peoples issues and help them sort out their emotions and troubles, however there is not, the closest we can get is by using {time and insight} to heal our wounds.
