I do understand that completely, I definitely prefer having someone around to talk with, spend time with, share ideas with. I like to be held.
I wouldn't advocate being all alone. I would cautiously advocate being with someone who you actively enjoy doing things with, and maybe there is a way you can find common ground when you get together and build that set of interests.
It doesn't have to be non-stop. Bob plays golf, I don't play well enough to play with him. So he'll go out all day long to play golf while I work. But then we'll do things together when he gets home. So he definitely has outside interests. But we do share interests.
