Ya, I think they say it takes a person 100+ times (I can't remember the exact number) to say they're going to leave a relationship before they actually do. I het that fully and also about wanting to hold on to the positives.

My point was less about you and more about his interpretation to what you're telling him. I'm wondering if you've lost credibility with him by these empty threats which makes him less likely to want to make changes because he (potentially) doesn't take it seriously.
