I am positive that to see someone over a lots of years open the door to another level of exchanges.
I lived it many times. We are buiding a respectful and powerful level of exchanges in a non-judgemental relationship based on pleasures build over the years, and this is very, but very nice. I call it "true connection"
I imagine there is people who are made for this, and other not. I hear that some are just afraid to become to attached also, apart to be bored. Maybe some other are more the "bee kind" who like to visit from a flower to another flower, smell and taste a certain difference, and other who just like to be conservative.
I am still seeing from time to time, someone from my beginning, and that's been 8 years that I am around. Some others from different amount of years.
I have this type of personnality that I adore people, especially men, and those particular friendships are important for me, even if we remain in the limits of an agreement without string.
If you want a couple of examples:
Many years ago, one of my favorites at that time announced me that he was stopping to meet this way, and I was sad, really, I had tears. That was a really great pleasures to meet together and because of the nature of our agreement, I respect it totally, because this kind of encounters are to be all free of any obligations, but I appreciated a lot that he took the time to write to me and talk to me how he took his decision and everything. When you are kind of near with someone, that's really apppreciated to know that we won't be seeing each other anymore. (and I guess that's something normal to happen in the kind of companionship I am offering, not based on "services" but on "experiences")
I have another who work internationnaly and it happened, he was taking charge of another territory, and won't come anymore in Canada. He took the time to write to me to let me know, and wish me well. We were seeing from almost the beginning and I have been his first companion, and even if he had a lots of adventures with others, he kept to meet me each time he went to Montreal.
STN, if you are not happy as much as before when you are meeting someone, that's enough of a good reason to change.
That's strange for me, because from a few months now, there are few gentlemen who come back to me after a couples of years not seeing each others. This happen too. And that's fantastic to see each other after this delay also. Everything is possible.
