Spartan....WoW I just read your first posting and it hit home. Very similuar sitch. Married out of HS for 15 yrs, I like to talk out issues right away and move on ,and she stonewalls and is emotionless to a degree. Her parents are to thank for this..Her and I are definetly opposites but I always felt we made a great team that way. I found an EA 10 yrs ago and she felt bad and admitted it to me. It took me a couple years to regain trust of her but i figured I had to to move on.
Now years later I think her "love tank" was empty due to my not filling it the way I should have. She felt she had to go elsewhere to get it filled. I needed this 2x4 I guess. At least weather it with this R or another I wont let that happen again!! I also fear that she feels too guilty and ashamed to try to make it work with me right now. She knows I don't deserve that and wants me to be with someone that won't do that to me(she has told me). Right now I think its easier for her to walk away and built a new house than rebuilt the existing one with "good" bones. Sorry I'm in construction:)
But back to your sitch I'm pulling for you! Sounds like she may be coming around but don't get your hopes up. Cause we both know by now the roller coaster ride up is great but the downside is a real B#@ch. Give it time and keep doing what your doing. I have my fingers crossed for you!
