It is one thing to stay on polite terms with an ex.
It is an entirely different ballgame to invite your ex to your wedding.
Take Valerie Bertinelli, for example.

Former power couple Demi Moore and Bruce Willis attended each other’s weddings to other people.
(We wish we could all say the same.)
While Charles might have loved having Camilla at the ceremony, Diana decidedly did not.

To this day you know vivid memory," the princess recalled.
Still, it was kind of strange to see him there.
So the affair went on until Charles married Diana, and then picked up again in 1986.

William even spent one summer vacation with Craig in Kenya, despite Catherine’s reservations.
This was when King Charles III decided to step in and give his son a much-needed talking-to.
Hunt and William dated for a while before Princess Catherine dazzled William at a St. Andrews fashion show.

Catherine famously showed off a sheer dress on the catwalk, and apparently, that was that for Wills.
Those who keep tabs on royal exes will know that Hunt moved on with Nicholas Wilkinson.
William dated Musgrave in 2001, and the relationship lasted for about a year.

After they met at a party, they started what Nicholl calls a “passionate romance.”
It didn’t last long, and now Musgrave is happily married as well.
William’s relationship with Farquhar was quite different.

Nicholl described William’s relationship with Farquhar as an “innocent, tender romance.”
Farquhar returned the favor when she got married 11 years later.
All’s well that ends well.

Before she started dating William, Catherine was in a relationship with Rupert Finch.
He wasn’t terribly sure if she was interested," the source revealed.
As we now know, William eventually stole Catherine’s heart, and she and Finch parted ways.

They remained friends, however, and as a result, he scored an invitation to her wedding.
He returned the favor when he tied the knot with Lady Natasha Rufus in 2013.
Recently, more details about their relationship were revealed, more specifically about why it ended.

We’re glad they stayed friends, though.
Their relationship began to fizzle after he returned from Afghanistan.
Harry and Bonas clearly had a strong bond, but they ultimately decided they worked better as friends.

Believe it or not, Kingston’s ex is none other than Princess Catherine’s sister, Pippa Middleton.
The royal world is a small one, indeed.
It makes sense, then, that he returned the favor when he finally tied the knot.
