You should have things that you together but also separate interests. There is the saying that if you love something you have to let it go to let it grow and if it comes back to you then it is yours to love but if it doesn't it never was. I think as someone mentioned previously it can also depend on the culture you are raised in. But not everyone is set to do clingy and needy and others like that type of person. They just have to find each other. It take honest communication about likes and dislikes before you are to far in.
