Well I believe that there can be a certain infatuation between two hubbers online. No, hubages isn't facebook nor a social network; it's a writing/reading space where people can sometimes find other people with the same interests, smart men or women, you name it; and that creates an attraction that only remains in the "infatuation" stage.
In spite of the fact that both parties have decided that it is a relationship, that you're boyfriend and girlfriend; that just can't be a REAL relationship with a long term result. There is a lot of needs in a real relationship that can't be satisfied via internet. And I'm not talking about sex or anything, I'm talking about hearing each others voices, smelling each others perfume, tiny details that make real love come through.
By no means is it wrong to flirt online within hubpages, but everything has a limit, try to be more private with that but If you insist on showing your love on "public" just add him/her to facebook and publish on his/her wall.
If you are on a virtual relatinship, there's nothing wrong with it but respect hubpages boundaries, don't forget this ISN'T a social network.
