Mr. Breakdown

I have a problem. I fall in love too easily and I NEVER let go. Even while I am in a relationship, I can't stop thinking about the mistakes that I made in my previous relationship. I have had three serious relationships over the course of six years. In the following two years since my most recent break-up, I have come to realize that I open up too rapidly and it scares people off. It isn't intentional, I just remember how happy I always saw my parents and I desperately want that in my life. I am 26 years old and single, watching all my friends getting married and having children, and I am alone.
