Jackie dear - time for the big Act As If. H needs to see that things will be different if he comes home. That he'd be coming home to an exciting nEW R, not the same old one.You need to keep up the 180's and pique his curiosity. Remember, too, that his grouchiness is probably a symptom of his depression - I find with my H that the happier and more playful I am, the quicker those moods pass- whereas if I REACT to his mood, we both get grouchier!
Make some big future plans with H. Vacation, training for athletic event? Read the Five Love Languages with him and talk about what his are. Meet his needs. Go out without the kids - heck, go away without the kids. Work hard on your diet and exercise.
