You Brought That Upon Yourself
There are some things that happened in our life that we don’t like so much, but we have no one else to blame but ourselves, because, frankly, we brought it upon ourselves. An example would be how we failed that math test that we had because instead of studying, we stayed up all night playing video games.
This is also the same in marriage. You chose who you wanted to marry and you married them, so deal with it. You chose to have an affair and end your first marriage, so deal with it. You are now repenting because the first one was actually the better marriage but you can’t go back to her now, so deal with it.
