Unwanted longing for companionship

First, no negative, cynical or put-down comments, please.

For the most part, I am accustomed to my own company and just keeping myself busy to pass the time, but sometimes there is a sort of longing for a significant other, though I have accepted I wouldn't have the right stuff to make it happen (money, own vehicle, job, social connections, etc.) and I ignore and quash those feelings by keeping busy.
