Thanks for sharing your story Joannie.
From what I understand, you are in a small village in France and the OW is also living very close to you. Is she within walking distance?
Since you are in a small village/hamlet that probably means everyone in the village knows everyone else, and what is happening in their lives and homes.
Is the Affair common knowledge in the village?
Does the OW have a Husband (BH)?
You say that you feel very uncomfortable when you go out.
Are you a newcomer to the village or is this the home place of either you or your husband? Do either of you have family nearby?
Your WH is still in contact with her. He becomes upset when you ask him about it.
It also sounds like you are isolated, having lost friends and family over this.
Do you have any friends that are only your friends, and not also those of your husband?
Of course you don't feel happy and a bit like you are going mad. He is asking you to trust him, when he can NOT be trusted.
He is still talking to her because he is maintaining the Affair. Even if it isn't still physical.
He is maintaining an emotional connection to her, at the very least. By keeping his connection to her, he is making it more important than your happiness and well being.
The problem is not how attractive or sexy you are. You are enough. The problem is that he lies and hides things. He is the problem.
He should not be in contact with her. At all. Ever. There is no reason for you to trust him if he is still in contact with her.
I am sorry
