That man wasn't the man of your dreams -- the man of your dreams is head-over-heels in love with you and absolutely thrilled to be a part of your life.  The one-month guy was just a diversion.

I wouldn't worry to much about not yet having been in a "serious relationship" as long as you have managed to make and maintain solid friendships over the course of your life.

But she can also learn a lot from these romantic relationships.

You can learn a lot from friendship-relationships too, so there's no need to feel that you are relationship-deprived. Also, if you are having a hard time getting over the guy who was around a month, imagine what it would be like to get over someone you'd been with for years.

I wouldn't throw in the towel yet. Maybe you should just try to hold onto it a little less firmly. So you're not dating anyone right now -- think of other ways to enhance your life. What do you like to do? Make time to do more of it, whatever makes you happy. Join a club. Spend lots of time with the friends you have now and also make new ones. Go to parties when invited. Exercise, learn a language, live. Make your life the happiest and most fun you can -- then when you meet the guy you want share it with, it will only be that much better.
