Tam, (is that your name instead of big number?), hopefully you have since been reassured I'm not your husband, writing on your thread. The walk-away doesn't generally care enough about what the LBS is doing to even look.
Listen to the excellent advice of the other long number.
Anyway, I'd love to give positive vibes. I don't think your situation is hopeless, but I do think it's too early to worry about positive vibes. A lot of things have to happen first....your H needs to work through his issues, you need to work through yours and establish your own identity (as you suggested to Tam), gain some confidence, recover your self-esteem, and become perfectly happy on your own. That takes so much time that you better get cracking.
