I want to call out Grace's thread here, and compare it to mine, to illustrate a few points.
Grace is charging ahead and her H is running scared, big time scared. That is what DB predicts will happen. Is it real, is it temporary, does it mean anything, who knows?
I have not charged ahead first out of hope/expectation, then fear, then legal advice not to. OD is scared but still can't bring himself to do anything about it because he feels no pressure to have to do something.
Don't see a few small changes and lose your perspective. You can sit around hoping forever, and it probably won't do any good, and it probably won't bring him back.
Moving on with your life and finding your own happiness does not foreclose the possibility of a future reconciliation, unless you want it to. What does that look like? It is different for every single person. More than anything, I think it is about creating your own boundaries for how someone in your life is going to treat you, or not be in your life anymore.
