“My husband and I mixed business with friendship.

Long story short: Our real estate broker/banker and supposed friend took our home.

My husband was a self-employed contractor who was building homes in his ‘friend’s’ new subdivision.

We didn’t cover ourselves with a proper contract; we should have gotten everything in writing.

Apparently, we were on the hook for a lot of compound interest.

We lost 20 years of hard work and savings that had been invested into building our family home.

All just gone.”

“Fully believing that my career took priority over other things like getting married and becoming a parent.

“I got involved with a married coworker after he pursued me for a year.

Even so, my coworker would still tell me that I was the one he really loved.

She harassed me daily, but I never entertained her wild antics.

This went on for three years.

It was a hard lesson to learn in my late 50s.”

He admitted then that he never actually had a new job lined up!

I gave him some money and respectfully told him to move out.

We don’t talk anymore.”

That’s one of my biggest mistakes.

Of course, there were speed bumps in our marriage, but that’s just life.

Now that my wife is gone, I miss her terribly.

It’s too bad it took too long for me to learn this.”
