My wife is polyamorous while I am monogamous to her. She has always been poly, even before we got married and it was very important for her to not lose her freedom when she gets married. I have always been quite supportive of her relationship and being good friends with her boyfriends. She only has one boyfriend right now and they have been together for more than 2 years now and she spends weeks at his place often. She tries to keep the time split 50/50, but recently she has been spending a bit more time with him than with me. Our friends know about it since he posts stories/photos with him on social media(nothing nsfw though) and her relationship with him is kind of public, they even have their own friends circle. I went to visit her last week as she had been staying with him since almost 3 weeks.
