Lou, Just as a thought experiment, I want you to dream about what you would do, what goals would you set, if H suddenly evaporated off of the planet?
Just take him out of the equation for a moment and ask yourself: what do I want to do with my life? What is the path to financial security and personal fulfillment for ME?
As a homemaker, you relied on your H to handle the finances. Unfortunately, as you've learned, that trust was misplaced.
In any new relationship with him, you're going to want to be in control of your financial future. You've got 20 more years of working ahead of you, if you retire at 65. You can accomplish a lot in twenty years.
