My biggest regret about getting married

‌I married her based solely on her looks.
She was 170cm tall, had a gentle appearance,
and was good-looking enough to be told she resembled Ha Ji-won.
Her family was poor, so she couldn't bring anything to the marriage,
but I married her with nothing but our bare hands.
Because it was such an unbalanced marriage...
My in-laws and her family provided a massive amount of support,
but then I found out she was having an affair
and even managing a secret slush fund account.
I truly cannot forgive her.
Since they helped us so much,
at the very least, if their daughter started an affair,
they should have tried to stop her.
Instead, she even testified against me in the divorce lawsuit
and actively stepped in to fight for the division of assets... lol
It is right to marry someone where the two families can align with each other.
Even if I tell this story,
I know you guys on Bul-Pener won't care anyway,
but I will give you one piece of advice once more:
At the very least, marry into a family with a similar level of wealth.
This is truly an absolute truth.
