Reading through your sitch, it's hard to figure out where you need help. You say that there really hasn't been any reason for your W to leave which makes it hard to pinpoint problems.
We need more information . What were things that your W complained about in the past? Even if it's a small comment, write it down here. We need to hear about the WORST things that came up in your relationship.
How are your interactions now?
