Most do not have a squeaky clean past and many have difficult experiences to work through. The more you clean out your own closet, the lighter the baggage you will carry into your next romantic relationship.
If you don't feel ready to take the leap quite yet, you shouldn't judge yourself either. I sure don't. Only you know whether you should break up with that person already or not, but what's more important is that you know you can.
After a breakup, it's so easy to feel depressed and alone. It's important to take matters into your own hands and pull yourself back together as quickly as possible. Realize that while it was traumatic, you can go forward and move into the new life that you want.
So there you are, probably making some spring salad, and he walks in and dumps you when all this time you probably wanted him to put a ring on it. There is never a good time to break-up with anyone, but consider it a gift.
As someone who's received many "breakup" letters, emails and even texts, I do consider myself somewhat of an expert. It wasn't until my historical studies at Rutgers that I realized that America was founded on the ultimate breakup letter in history: the Declaration of Independence.
