welcome aboard...you no doubt know (if you've been reading) that this is not an easy road to walk. questions a plenty...sometimes we find the "solution" and sometimes we don't...there are good days and there are bad ones...what will happen in the end? no one can possibly know...you've got the tools now it's time to start building!
other than going to c (mind you it may be good it may be bad...depends on what type of c you go to) what are your plans?
as far as how long before she believes your changes are for real? time will tell.
