Hey Wendy. What ever happens with your sitch, as Bond mentioned in my thread, no... it is not necessarily a mission for people to be a couple.
Not sure if you saw, but 25 also posted a message for you in my thread. You may have not seen it as it was on the last page, at the top.
Due to your circumstances in upbringing, you may have come to the conclusion that once you were done taking care of your family, it was your role in life to keep taking care of people... thus you went from your family, to the room mate, to the husband, to the kids... and with the kids gone, you may feel you need to keep that role with your H...
Yes... People do crave companionship in some form. One is for pro-creation... another for companionship... general, homogeneous discourse...
But most people, at the time of puberty... are driven NOT to be a couple... but to be an individual... to have their own life... to be SINGLE...
As you may have never had that in your life. it may be something that you are only just learning for yourself, now...
Again, that doesn't mean you have to D... it doesn't have to mean you stop doing things for H... all in the name of finding yourself...
You appear to be doing a decent enough job stretching your legs on that...
Just keep doing what you are doing, for the time being... because IF you end up D... You DO NOT have to get into a new R... it is not your purpose in life... it is your CHOICE if and when you might want it...
