I'd probably defer to the guys with more experience with MLC, but when I read your story I think a)that you handled it fine by telling her you love her and b) that you might not see substantial progress until you get some time apart. I get the sense that she is always going to compare the grass is greener (ie away from you and the kids) with life at home until she gets apart for awhile (and I don't think a day or two will do it). Also, she probably has depression and/or PMDD and needs meds. Hopefully she gets some help. You're doing as well as you can under the circumstances, certainly better than I would; I'd have said, "I think maybe we need a couple months apart."
