Quote: I thought communication in general and MY anger/intimacy issues were at fault for most of our problems.
So ... because your W opened up to you twice in conversation and you've addressed your anger/intimacy issues, everything's been fixed and you only need to maintain all the changes?
Forgive me for being skeptical and for how this sounds, but I think your marriage probably has more problems than that.
If your W won't go to MC, maybe you can bring it to her. By that, I mean that maybe you can read some good stuff together -- a lot of books also have good questionaires that you both can fill out and compare.
You've already read Mars/Venus, but what about 5 Love Languages or His Needs, Her Needs? I think that your W needs to be willing to do some work to improve your marriage -- it shouldn't all be you.
The LORD is near to all who call on him, to all who call on him in truth." (Psalm 145:18)
