Been with partner for 3yrs a week ago I found out he had slept with my best friend 2yrs ago. In the time he cheated he lost his dog & grandfather. He then tuck comfort in talking to my best friend about it as she made him believe I didn't understand his pain & I was toxic. Because I was also grieving the loss of my children's father to suicide so we was both in grieving in different ways. He couldn't be more sorry it was only the one time and has let me ask any questions I have but even with him being so open and letting me get through this am in such a black hole of emotions. Even with him being so open and honest the pain is killing me I do want to try and make this work but I am not sure if I can with the amount of pain it's caused me.
