No, I don't understand why that would be necessary. I would only close off the person who hurt me. Yes I might take a break from looking for a relationship but it's not like I'd suddenly start avoiding men at all costs. I'd still want to talk to men and befriend them.
Oh. Yes. Sadly. There is literally only ONE guy that I would possibly change my mind for except it's almost impossible with him. Otherwise, I have totally given up and am convinced I would love any woman before I love another man.
