After 15 years of monogamy my DH has convinced me that we can be happier in a more open relationship. This followed his confession of a number of casual sexual encounters and a deeper relationship with a woman living in another country (yes, all this info came at once). He claims that he needed to "get the casual sex out his system" as I had been his first proper relationship and we married young. For him it was a release and a realisation that it was in fact no big deal and made him appreciate me more. He says he loves and is deeply committed to me and our children and this other relationship is a deep friendship which is helping him find himself. The argument is that one person cannot provide everything for the other. Since I realised that I could accept him and that "fidelity" had been a something of a "sacred cow" for me and I could accept to let it go, we have had the most passionate sex for years, the best conversations and a wonderful new intimacy. Are there any women out there who have had any similar experience - did you go on to have other relationships yourself? Did you ever cope with unwanted feelings of jealousy even if you had accepted it? Is it really possible to change the basis of your marriage so fundamentally and be happy? Opinions please!
