So my ex and his new wife go visit my son ex step son....I am ok with that but I feel so betrayed because ex asked my son if he and new wifey spend the night there.My son and I get into a big text fight over it....I dont mind him visiting with them but it hurts that my own son didnt even consider how I would feel.She was the homewrecker that ended my 25 yr. marriage and yes I know all about he was looking for someone to have an affair but the same one he had an affair with 18 yrs ago.am I over reacting? and she is ther holding MY grandson. Feel very betrayed....why do I feel this way...why did I give her any space in my head and lash out at my son?
