I used to do that... fall so hard and deep... I didn't understand it. And when I did fall, it was often with someone mentally ill who was very broken and had deep emotions. It was all very painful and confusing to me.
While it isn't conventional, I feel better these days by not having a committed monogamous relationship. Once I let go of the "you must devote all to one person" aspect, and just love whoever, whenever, and how many people I want...I'm so much happier, and I feel my love is healthier. I think that at some point in the future I might settle down with someone just for logistics sake of getting old together, and if I do happen upon "the one", I believe he would have to be a healing type like I am, to where our intensity calmed each other down. I've heard some here state that two empaths shouldn't be together, but I've had a close friendship with a healer, and it was a very neutralizing and peaceful...I will not commit to someone who doesn't understand or appreciate my "intensity" again.
