I will also add, these past 5 years have been the hardest and most rewarding of my life in equal measure.
Only the other week, and out of nowhere, I said to myself "I am now ready to be someone's partner". I had to go through that pain, that discomfort and that loneliness to be able to be in a postion to really appreciate another person for himself, to have great boundaries, to know what I want and be able to ask for it, to let go off the little stuff and the drama and treasure the important bits of a relationship. I know that any serious relationship I have in the future will be much, much better than those that have gone before, even if they don't last. Because the crap ones will not develop beyond a few dates and the great ones will finish for grown up reasons.
