Absolutely agree with this.
I had many intense relationships and they were all sort of like an addiction. Not good for me, but desired intensely, leaving me craving more and hating it at the same time.

Its not fair to anyone and really, being in that relationship is not necessary right now. However, also beware of chasing down the involvements with others that stimulate the excitement factor like a bad drug. THAT's not a good thing either.
