You should think a hundred times before getting into the bond of marriage. If you are happy to be with him and you can envision yourself to be his wife and him being your husband for the rest of your life, maybe you are ready to get married. Knowing that you've been with each other for 7 years, then there aren't a lot of adjustments to make since you already feel comfortable with each other and somewhat, you know about each other's behavior. It is up to you to really decide. Love will eventually get you into marrying stage but if you are not sure yet, then don't!
