Very positive, A, but let me caution you too. Remember, have no expectations. I am not by any means saying that this isn't a wonderful thing, but just watch and wait. See what he does.
And if he follows through and does come back, MC!!! You will both need that to get the marriage back on track.
It could be that your H is realizing the grass isn't greener...being alone is a hard thing. But being stuck in a rut is worse, so make sure you listen, validate, and hear what he is saying. You will get your chance to voice your feelings as well, just make sure you listen to his...
Im still standin better than I ever did looking like a true survivor feeling like a little kid Im still standin after all this time and Im picking up the pieces of my life without you on my mind..
