How do you know that these a person is the right for you, space needed for your life?

I mean do you have feelings like maybe you are making the biggest mistake of your life? by getting married with  to someone? how How do you know if you are sure?

I am confusing confused about what things we need to put in a the balance and compare decide what has more weight? Should we be funny or be serious? Should we share the same jobbies hobbies or have differents jobbies¿ hobbies? How you are can you be 100% sure or will you never are be 100% sure that is the love of your life?

These are questions answered by the heart.

Sharing some hobbies and have some different hobbies is often the best because it gives you something to do together and something of interest to talk about that the person won't already know.
