I've lived with my dual... The only problem with that relationship was that it was claustrophobic. We only really wanted to spend time around each other--we didn't go out much.
That said, I don't know if that's peculiar to EIE-LSI, or if it's something that applies to SLE-IEI as well.
Maybe because your dual is LSI? When I dated an LSI it was similar to that, we wouldn't see other people much, just the two of us.
Although I heard similar dual stories, that there is little need for the outside world if you are with your dual.
Looking for an Archnemesis. Willing applicants contact via PM.
