So far, so good with the 180s on my end. We communicated via text over the weekend, and the messages were funny and playful (but not suggestive, which would be distasteful). I initiated most of the contact (which is something he felt I didn't do enough of), and he always responded quickly. I think his quick responses are a good sign. It felt like our regular text interactions from the olden days, which is a step in the right direction.

However, I fully expect him to pull back soon and/or start questioning the worth of our marriage again, so I'm working on being prepared and not taking it personally.

Thanks for sharing your experiences. I just have to keep getting myself to think, "Am I doing more of the same?"
