One of each for me.
XAH left us (our three kids and me) for a girlfriend (I can't call her another woman because she was a kid herself, barely 18).
Later, I left xabf. By then I was older and wiser and left before it became a marriage. Maybe 'wiser' isn't the right word choice. If I had been wiser, I wouldn't have let myself into the relationship in the first place.
