My divorce was certainly my most difficult breakup. It was the most difficult thing I've ever been through. It was more than just the end of a relationship...it was the complete breakdown of everything I ever thought to be true, or that I thought I could count on. My whole world collapsed.
Or at least, that's how it felt.
I learned that things are often not as bad as they seem. You may have to go through something awful to get to something wonderful - but the bad is just temporary.
I learned that independence is important. Even if you don't have to handle things on your own, you should be able to do so. It makes you stronger as a person, and it makes you a better partner.
I learned that friendships are the most important relationships you can have. Family loves you because they have to. Spouses aren't always as permanent as you might hope. But friends... they will get you through the darkest times, even if they have to drag you.
I learned it's OK to need help - and it's OK to ask.
I learned that a change in a relationship doesn't necessarily mean the end of the relationship.
I learned that love comes in many forms - and is precious no matter how it's found.
I learned that what seems like the end is often the beginning to something even more wonderful. We may not always understand at the time, but things really do happen for a reason, and you really are right where you're supposed to be.
Most importantly - I learned to believe.
