welcome to this site, jumpchump.
you know what? you are NOT a chump. you are a caring, devoted and stand-up kinda guy...they way you feel a husband is supposed to be.
as to your query about worrying for the rest of your life....if your wife truly chooses sobriety, and recovery from what ails her, you will see a different person. really. then you'll know.
and if that happens and she begins to turn back into that other one....you'll know that as well.
you both have work to do.
we're here to support YOU.
