WHAT?!? She treats you like crap most of the time, what do you mean with "Other than all that"? "All that" is practically your whole marriage.

If I didn't trust the Dr., this story would sound like made up. Alas, marriages like this are sadly true.

Man, that's not love. That's dependence, obsession, addiction.

Real love enlighten, nourish and uplift you. What you are in, instead, looks more like "sweet poison"... without even being sweet.

IMHO, get therapy ASAP, and learn to love and respect yourself. It's never too late to start doing that :-)
