neither, but hmmmm if आप want to get married with some one, and if that person does want too, then...fak wait, if आप really प्यार each other with a person then it just प्यार bruh but to answer your question, its neither really.
It's 100% a choice. Society pressures people to do a lot of things, but आप really don't have to do it don't want to if it's just to please others. Paying taxes and paying rent every महीना unfortunately are requirements.
Neither. Marriage is a human concept, but if people WANT to get married to with someone they love, than that;s their choice. I personally don't desire marriage, and don't feel obligated to participate in it.
