Your wife has given you a great gift, even if you can't see it right now. You have a great opportunity that most your age do not get this early in life. You have a chance for huge personal growth.
Completely agree w/R2C.
Not sure if you're ready to hear this, but...she's 1) showing you who she is very early on (before you have years of marriage and kids together) , and 2) giving you an incredible opportunity to dig deep and transform yourself and your life.
Take advantage of this incredibly difficult situation to make yourself a much better, attractive, valuable man. IF you do that you'll look back in a year, 2yrs, 5yrs, 10yrs and realize what a defining moment / inflection point of your life this is.
