It's important for people who plan to share their lives to have things they enjoy doing together. Having a few separate interests is almost as important as having things in common. No matter how in love you and your partner may be, it's impossible for two people to spend every waking moment of their lives together doing the same things, and still remain sane. These, especially if they're of a highly emotional nature, can wear away at even the strongest bonds of love. As relationships develop the objectives change.
People grow together, but they can also grow apart.
The important thing here is to be sure you and your partner stay in touch with each other on any new developments. Some families are more tightly structured than others. But you must be willing to put your present partner ahead of everyone else. You aren't ready for a new commitment if you haven't yet dealt with the old ones. Nothing is as shaky as a partnership founded on desperation.
