I get where you're coming from, gogofo. My wife recently told me that she doesn't see a future for us because things haven't changed in a positive way for a year. At the end of the day, we have a wonderful resource here that our partners don't have. We have information, literature, positive, pro-marriage people who support our efforts and constructively criticise our errors... our partners, for the most part, are likely relying on ill-informed people with varying attitudes towards marriage and relationships.
Hang in there. It's not much fun but you've made progress before and I'm sure you will make progress again. Just gotta be patient and keep being the new-and-improved you.
