I am truly sorry you are in the position you are now in. It can be extremely hard for many of us to really understand and empathize with a WAS, simply because these are the people who have helped to hurt us and brought us to this site too. However, it is really great that you have done some introspection and now feel like your choice to WA was the wrong one and would now like to work things out. Yea for you (and for your H, if he decides he wants on board)!
I'm wondering if you can provide some insight as to why you've decided to reinvest in your M. What brought you back from the WAW mentality and what put you there in the first place? Is your drive to come back influenced at all by H and changes he's made, things he's done/is doing, etc? Knowing these things would help many of LBSs out, but would also help us to understand your sitch better and give you some advice.
You said you've had a lot of growth over the last 8 months -- does this mean you realize how you've had a part in the crumbling of your M? Do you think H has come to look at himself and see where he has had fault?
Hope to hear back from you and that you get the support and help you're looking for!
