This is the most common issue faced by most adults (be it male or female). From my personal experience, I can suggest one thing to you if you want your family to understand you, understand them first. Ask them why are they rushing on such a thing, why they want you to get married. Explain to them your point of view, and why you don’t want to marry, and show them that yes you’re doing something or planning on something where you can’t involve anyone and are not ready to be in a relationship. Listening to your parent’s point of view and explaining yours will help you a lot.
