I am 43, DW is 39. We have been dating for six years and married for three and a half. She is white, I am a Egyptian Christian (will be relevant later). She does not know what MN is so, I can be frank with details.
Our issue is her male friend of 5+years. Said friend clearly has designs on my partner. In conversation he has (playfully ) confessed to a relaxed and enlightened attitude towards such adulterous relations, albeit in a more abstract context. He is also just a bit too familiar with my wife for my liking, i.e. massaging her shoulder in my presence to which she acquiesced. In the last few months, they have been spending time together i.e. dinner parties, cinema (they share interest in certain things), and other events I cannot make owing to my commitments at work and cleaning up after my alcoholic sister's mess (she has three kids I practically co-parent, they live a mile away, I am there every three days for about an hour). I began to be really bothered when, one night, whilst I was abroad for business, she locked herself out of the house and informed me that she would spend the evening at his. I objected, offering to book a hotel room instead. When she refused, I went ahead and paid, presenting her with a fait accompli. Guess what? She says oh well! Goes to his. When I remonstrated with her I was told this was not the Middle East. She was not my property. Admittedly she apologised for this and bought me gift.
Things came to ahead when on talking with said friend at a dinner party he made mention of a disease I had in early 2000s. I was astonished and hurt by the revelation that she freely shared what was for me a big burden I carried on from a dark time in my life.
This month, I booked a week off from work to recuperate. When she came home, I sat her down and gave her an ultimatum. My terms? To cut off said friend forever, or it was toast. I was off. I even showed her (admittedly fake) housing arrangements I had made should she refuse. Cue a breakdown. Cue tears. Cue apologies. She said has been her friend for 5 years and has been there for her in desperate times. She says she can have a talk with him but by no means will she cut him off.
Thoughts?
