letting go - really that simple?

I mentioned before how this practice, this immersion has left me with such an incredibly open heart...that is at once both exciting and scary. It has put me in a very vulnerable place and as a result made me reevaluate the kind of people I want to surround myself with...
Lela has been in full swing for me the last few weeks. Wanderlust was a weekend so full of love and I think that i came down hard, coming back to the real world.
Some people I called friends turned out to not be who I thought they were, leaving me stranded in Yellowstone and having to pay a park employee to drive me to the airport in Bozeman.
I opened my heart to someone I cared about and trusted deeply and although I was able to be mindful and open, his heart was not in the same place and I ended up with a broken heart. This feeling is mostly because I feel that I am closed to him now, I have lost an intimacy, a friendship that had been building for a long time.
But the point is that the tools of meditation and mindfulness, coupled with the open heart this practice had given me are invaluable. I have always had an extremely hard time letting go of these things...cried for months, feeling betrayed, hurt, down on myself (whats wrong with me? , why am I not enough for this person?). But yesterday I took a deep breath, made up my mind to let it go, and did. I am a bit weirded out that it was that simple, but it was. Mark says "It really is that simple, once you move through the process. Then you discover that the struggles are all choices regarding how we choose to feel about our relationship with all life; and find it simple to accept a path that lets go of most of that twaddle and silly stressful nonsense."
I haven't cried since and I feel strangely calm about the situation. Not to say I'm not still sad, but it is not consuming me as it had this past week and in the past. I feel peaceful.
