Sometimes you need to repeat yourself. How many times? As many as it takes. You tell us these things about how you feel on here, but I wonder if you tell her all of this as well. I mean reallllly tell her.
I see the cynacism, and with what you have gone through, I can understand. You have been working hard, and you don't see her working that hard. Yes, trust me, that she is working hard and you may not see it outwardly.
Bottom line, don't give up. Divorce will not be the answer for either of you. Make an appointment on your own to see a counselor, and ask her to come. Find the dates for Retro and sign yourselves up, put it on the calendar. You can always bow out of it, but have it forefront in your thoughts. If you want her to take working on the relationship seriously, the way you want her to, then you start getting it going. Because I think what she is doing is trying to emotionally connect with you, and after what she did, it is hard to do. But, yet, I see her doing it little by little.
I'm not trying to argue either. I'm just trying to help.
