If this is hitting you so hard maybe it's not too late to plead temporary insanity & mend fences. You meant a lot to each other before, you had kids together & did life together. Are you looking back & seeing anything you could have done differently? See if you can start now, better late than never. She may be full of regrets on this too & may welcome such a move from you.

OP be real. When you find someone who likes to discuss politics, she will come with other baggage. You are now trading in your used car for someone elses used car. Think about it.
