I misread what you wrote. Sorry, you are only separated.

But, I would caution you. About 2.5 years ago, my soon to be ex gave me the I love you, but I am not in love with you speech. This separation sounds like your wife may be positioning towards divorce, although not sure. A lot of what I said can still help though.

Hanging in limbo can be its own hell. If your wife says you are boring, then why would you want to waste your time with her?

It seems to me like a choice is going to have to be made. It appears, to me, that your wife is not willing to reconcile at this point.
