There is neither right not wrong people. It's not because two (or more) person walk on the same path for a while that they have to for ever. At some point path diverge. One get something from this journey which will be of used for the next one. that's the way to grow. Life is beautiful, you always meet the "right" person at the right time but keep in mind that this has no mean to last forever. Life is movement, Life is change, Life is Love. For all those reason people, opportunities, and so one, come and go. This is part of the flux of life.
