Thank you for writing, just reaching out makes things better.
She was a mutual friend of ours while married so yes, he has been with her -though I don't believe intimately which I know sounds completely naive - for the entire separation.
Great question - thank you. The DB coach instructed me to have fun with husband, don't talk about her, don't give her any power, he is a pesky insect in my life etc. I was prompted to call the DB coach after my son called me by her name while reading a story before bedtime! AGH!!! Kills me I still remain friendly with her - she even sent me a birthday present. It is all so confusing because she is a nice person??
The crazy thing is that things between my husband and I are great and keep getting better, but it is hard to get closer and closer while people come up to me and ask "Hey is your H living with OW?". - This will be after a fantastic night out with H laughing, talking, kisses even etc.
So confusing.
Again, thanks for writing. Sorry you are here too!
