Were you this indecisive while you have been married to her? It is no wonder she wants out the way you are acting...
GROW UP. You are sounding like a little child here that wants his mommy....
Make some decisions here and live with the outcome.
You are a big boy. MAKE a decision based on being strong and confident...
I will give you a hint.... (get YOURSELF a lawyer asap and let him guide you regarding who gets what and so forth.)
You seem destined here to error on the side of being a wimp than you are of being too strong with her. If it were me, I would be taking care of Gucci right now. The kids are just another excuse she is using to get what SHE wants. Don't fool yourself.
