I am working through wanting to try a serious relationship with SW. He is not interested. It is very painful when someone does not want us in the way we want to be wanted.
Someone on the forum suggested that a 40 days, 40 nights no contact might help shift things back to friendship and help keep that friendship in general. I don't remember who unfortunately. So I am trying that. It's helped in that I am not constantedly reminded he is dating other people. But I don't know how things will feel when we are in regular contact again. Maybe physical or physical distance may help in the short term?
Also, are you sure she loves you less intensely than you love her? She may show love in ways you don't recognize.
