What motivated you to get married?

You don't need motivation when it comes to a decision of getting married, because once you said you are just motivated, someone may have just influenced you when in fact it should come automatically from your heart and you are settled in your own mind that you take the responsibility. Marriage is not something that you play around to get motivated or an action that needs to be persuaded, that is why you need to come of the right age to decide from yourself, and not because your parents told you so. Motivation is not the right term to use here but instead Decision. I guess you are also young to consider what marriage is and talk about it when you don't have an example to include when you ask the topic. But anyway, you're a newbie so welcome to Mylot world.

I'm not married by I live in partnership. We are happy together and maybe in the future we will decided to get married. We have stable relationship. We know each other as we live together since 5 years. Sometimes my partner call me wife because we live like married couple.

Marriage is a natural process that happens in one's life. I never needed any motivation but was mentally prepared when the age was right.
