Dear Emerald, I have been in a similar situation.
When I lost my partner I was told things that confused me and I found things that confused me. Information to do with possible affairs with other women. I was wracked with feelings of anger, sadness and resentment. These feelings came and went over time in intensity. I had always been loyal to him. I felt betrayed.
I must say though, that over time, all those bad feelings have dropped away. I don't think about them any more. No-one says anything to me any more. I think what sort of people were they to be so insensitive towards me to say those things at such a hard time anyway? Do I really want them for friends? In fact they dropped away. My true friends have stayed with me. I remember the good things that my partner did for me and I am grateful for the fact that he left me with a house to live in. Human beings sometimes do wrong things but we are all human. At least he didn't leave me homeless. I have had security. I have been able to move on, learn new skills, get higher education and better work opportunities. I have been able to raise our child and she is doing well. It has been a really difficult time for me but one from which I have grown and recognised the many gifts my hardship has bestowed on me.
I hope you can feel better over time and maybe even have a laugh about it with your friends and family later on. Love is the key. Forgiveness is the key to regaining health and happiness within yourself. Remember you are beautiful and unique and you are here to bless this world with your wonderful energy of love and light.
Lots of love to you and your family,
