Your description "relationship is the meaning of life for me" and the length of your relationships has me wondering if you don't come across as too intense...

Like too hard too fast, or too much too soon.

I could be way off base, but I remember being 22 and if a guy wanted me to be an integral part of his meaning of life before the one month mark, I'd be running in the opposite direction. Full speed.

Why, well for one, that's way too much responsibility to place on another human being, and 2, its just way too soon.

Also angry outbursts no matter how comfortable you are, are generally not expressed during the honeymoon phase and could also have played a role in why these girls ran off.

I agree that you should not make finding a partner the focal point of your existence, and that some kind of counseling will most likely be beneficial to you.
