Astrology can only provide a compatibility between two individuals by analysing the birth charts of both the individuals, but it cannot provide you with the information whether you would get married to a particular person.
As per your chart, there could be some friction or may be a temporary separation with partner initially after which you would both get along for your life. This could cause some delay in your getting married.
You have a happy family life with all the love and affection you deserve and that which you would give and share with your family.
