I knew that my new marriage was going to end badly and there was nothing I could do to prevent it except to cause a premature break-up.
Do you think that your marriage ended badly because of something that you did personally?
The love was gone. I don't think there was much I could do to keep it together.
Even though you believed that your marriage was going to go bad, destroying it on purpose wasn't correct. You should still try to work things out with your partner.
I should have married someone else.
Intentionally trying to ruin your marriage is a pretty messed up thing to do. Even if you would have rather married someone else, you should simply talk to your partner about your feelings instead of playing with their emotions.
