My wife for months had grew distant and cold with me, until a member of their family accused them of cheating on me (with no proof of it happening). Since then she has gone back to being her normal self around me with no explanation (some days going back to being distant), it's like the past few months never happened. Now she wants me to integrate with the friend group where the person she was accused of cheating on me with is apart of. Do I put this down to Premenopausal behaviour, or am I not reading between the lines?
