I'm sure you are taking this point of view now because it is all still very new (being free from the M) but maybe in a few years you will see things differently. Want someone to grow old with maybe. Who knows.
Oh, I'd say it's more like I'm "exploring" this POV rather than "taking" it. Whenever people talk about wanting someone with whom to grow old or wanting to be in a relationship so that they won't die alone, I reflect once more on what I learned studying mathematics which is the fact that human beings have no natural comprehension of probability or statistics. If you are a woman, you will probably not be in a LTR when you die. It doesn't much matter what choices you make in that regard when you are 42. If I was concerned about living alone in my old age, I would be better off making more of a priority of the tentative plans my sisters and I have made of purchasing a vacation home together. OTOH, I'm sure I would be overjoyed to someday wake up and discover myself in a relationship that had lasted over 20 years and been largely continuously successful but if anybody on this BB has discovered a way to get to that point besides just playing fair and having fun and not tolerating poor play from one's partner, I've yet to learn their secret.
