Spending more and more time together.

As you and your partner spend more and more time together you will learn a lot of different things about each other. Some things that you learn you will not necessarily like, but they are things you will have to cope with if you plan on being with that person for a while. I think it's best to find out each others quarks and flaws in the beginning of the relationship so that there are no surprises later. So, don't be scared, be curious and be open.
