Ok I agree 100%. The question then lands squarely on you. You proposed to your soon to be ex wife, right? Well. Mistakes were made. And listen, I could have done better picking a spouse the first time around too….(Ya know stones and people in glass houses….)
Part of life experience is accepting responsibility for our role in our circumstances in our personal lives. I knew my first husband 3 years but married him after dating 6 months. That’s on me. Had I waited I would never have married him. I ended up with 3 great kids and he’s an amicable ex spouse so it ended up ok, no War of the Roses divorce, he did not seek to tear me down financially, so I did pick a genuinely kind person who could see the bigger picture.
So own the mistake & learn from it going forward. One nasty person does not mean all women are nasty.
