I think that marriage isn't absolute - suppose your spouse talked 15 minutes every day with someone else or how about 10 or 5 - is a shorter time better? Does your wife spend meaningful time with you? Is this amount of meaningful time increasing, even if not always? Is there some behavior related to other people that is acceptable? Emailing? Does she tell you that she loves you? Or show it somehow? Maybe she needs more space for a bit.
It seems to me that where a person puts their time indicates what is important to them and that we can't require 100% of it always. Of course, there are unacceptable behaviors - sleeping with someone else, or having a prolonged emotional affair and no longer loving you - but we are human and can change and choose and come back.
Give it time, try new approaches, watch the results, monitor the improvements, and see where you are going (I've been DBing three years (!) and things are a lot better, but my wife and I still don't sleep together or touch - it is a matter of faith and seeing the good).
Hang in there - forgive if you can - be patient -
