Start a relationship the Halal way so that it can have Allah Subhanahu wa Ta'ala blessings and it will last forever. In sha Allah. A Haram relationship will be cursed from the start and will end in a brutal heart break. That’s why Allah Subhanahu wa Ta'ala forbids anything other than the Halal why because of the outcome and the pain you feel. SubhanAllah! He is only looking out for your most valuable possession (your heart), and what is best for you.
