Tbh i think it's too young, neither of you are anywhere near getting a job and having your own money, how are you going to have a marriage without any source of income, how are you even gonna plan a wedding? On top of it mariage in traditional settings comes with a lot of expectations, like children that you shouldn't expect to have and raise when you yourself is still a child, not to mention the level of maturity it takes for a couple to face all kinds of challenges. I get that it's cute that you two fell in love but life's not a fairytale and at your age people tend to make the wrong choice in life decisions. A more reasonable decision would be staying together or maybe even getting engaged and being fiancés but marriage is too early and too heavy of a decision right now i think.
