The most perfect person you will meet, might as well be the one and only. This person is really unique... and sometimes brags their name isn't "Amber." They have a good amount of friends but they can't talk to anyone new. Better make her your friend!
Someone who jumps from one relationship immediately into another one.
Serial monogamists can not stand to be alone and often suffer from vast commitment and insecurity issues.
Because they jump into relationships immediately after the previous one has ended, serial monogamists typically don't take the time to reflect on their behavior or why their previous relationships failed; thus, they end up making the same relationship mistakes over and over again.
