"After every relationship, it takes a while to heal when the heart has been broken. It has been really, really wonderful for me to realize that I am able to trust and love again. It's nice to see that life goes on," she described.

In 2019, Tessy revealed that she found marrying into royalty extremely difficult.

"My little cousin needed to change schools twice," she told Sky News at the time adding that her family "suffered greatly" with the media scrutiny.

"My twin brother was incredibly bullied at work — he still is today," Tessy continued. "My sister, my parents suffered, my oldest brother doesn’t talk to me anymore because of that, because it was too much for him to handle. That was when I married in, and when I got divorced, oh my gosh the same."
