I'm leery of pointing to anything I did as a good example of DBing. I've broken most of the rules repeatedly, and our outcome is definitely not assured.
We've always been able to talk to each other; listening has been the hard part. My wife is still angry about being neglected, and she's famous for holding grudges.
I don't really know what changed her mind towards working on the marriage. I know that our daughters are a big reason she's staying around. Plus the fear of making a hasty decision in leaving our relationship.
Probably the biggest turning point was when I dumped her. We ended up ML for the first time in months that night, and the next morning, things just seemed different between us. We talked about continuing our MC counseling, and now the topic of D and S don't even come up.
I don't know if her feelings have come back yet. We've been intimate once since, but we still have big issues. We're much more honest about somethings, but some topics are left alone for now. It's hard for her to display affection; something I really want. I definitely don't think we're out of the woods; the odds are pretty high against us really.
She's been gone for a week visiting a girlfriend and some family. I tried to give her as much space as possible on this trip, and hopefully it'll have helped her think about our sitch.
Prayer has helped a lot. Knowing that I can handle this, and that I'll be okay no matter the outcome makes it easier to weather the tough times. And I expect those tough times to last for quite a while.
