Not sure about telling my family, that would definitely will be the last nail in the cuffin. I wish there would be anything else I could do. Even if it just to stay put and give her more time to process her thoughts. But maybe that's just me fooling myself, some day she'll wake up.
Only you will know mate, when it is time to give up. Give her more time if you want/need to do so. It's only really over when you decide it is.
It is very tough to give up all hope isn't it. I too feel like a failure, and soon to be tagged with "divorcee" despite not walking away from the lifelong commitment I made. I think they're all normal feelings for us to have. It's just a shame the WAS don't seem to have the same issues!
Reality is that which, if you don't believe in it, doesn't go away.
