OK, so she's texting other man (probably more), and you spend all your time talking about YOUR faults?
I think you need more BALANCE here, JR. Yes, you need to own your own faults and shortcomings in the relationship. But self-flagellation, falling on the sword, and doing the Obama Apology Tour isn't going to garner your wife's respect.
And since women VERY closely tie their feelings of "respect" with their feelings of "love" . . . well, you can see your challenge.
Not a bad phone call. But try to create some distance now, and some STRENGTH.
