she told me how amazing I was I'm sure she was right about that...just doesn't mean much coming from her.
How profoundly disrespectful of your H to have her around you, and at such special occassions too.
You are very welcome here. Have you read in the Healing Library at right? What actions is your H doing now to regain trust? Is he seeing a counselor? Reading books to understand infidelity? Getting tested for STDs?
I am so, so sorry for your multiple traumas. Your anger is justified! How about you - do you have support now? Have you considered talking with an IC? You have multiple hurts to process - losing your friend and discovering this betrayal. Please take good care of yourself.
