My wife is having her second affair with a married man in two months. She's away with him this week at a band camp and I want to expose them but know that it will appear that I am controlling which is an issue with us. She states that it's part of her gradual breaking away from me. Over the last few years she's become increasingly angry, impatient, has a low frustration tolerance and is struggling to find happiness. Both her siblings and her father are bipolar and she's refusing to seek any treatment even though the symptoms are there. I have spoken to a psychiatrist 4 times now trying to get help who assured me that I have done all that I can and that she will seek help in her own time.
