No, I'm not talking about marriage counseling, I didn't know she was your love, just thought you "trusted" her. Use that trust! She will help you. I imagine (have a good imagination :-) that you are afraid you will hurt her in some way if you stay. I think you will hurt her more (and yourself) by leaving precipitously as you're planning. Give other people and yourself more credit than that! Stay and work out your feelings/worries. If that doesn't work, then somewhere down at about choice 4 or 5 will be wrecking everything by quitting, leaving, hiding.
