I am old, and I haven't fallen in love yet. I guess my tolerance for stuff is low. The best lessons that I have learned in life so far though:
1. Things will always work out.
2.Whenever something bad happens something good will come afterwards.

From all of the friends I have that are married now. Most met their husbands after breaking up with an asshole.

Let it go girl! Give yourself some space. Focus on you and on yourself. Make a list of things that you are happy with and things that make you unhappy. Focus on growing and appreciating the ones you are happy with and improve the ones that you can control on the bad list. There is only so much in life that we can control. The rest you just have to let roll and just keep on walking. You need goals and other stuff to focus on.
