This all sounds very abstract to me. For me personally relationship is about value. The value you provide to each other. I have been been married for 1.5y now and our relationship has grown a lot, however we are not having sex anymore, that is a lot of where value is coming from for me and eventually not getting any will kill me. So I will have to leave. That is what is worrying me. While everything is peachy and nice in the end it's about how I enrich her life, but if I can' get what I need I won't be able able to.

I am always surprised how people are so focused on what the other side is doing to others vs to them. All that matters in the end is your life richer with your partner than without. But I am probably just weird and not normal. I would love for my wife to cheat, for that would mean she at least wants sex and I could could deal with the problem.
