You don't have to want to get married. It's just that we very much doubt the OP is in love, it will barely be a relationship.
Going by that logic, no one should date each other unless they are 100% sure they are perfect for each other and their relationship is going to last forever. Tell me how someone would know that without getting to know the lady/man better. Dating isn't like marriage, it doesn't symbolize your endless love and devotion to each other.
And if this is true, why do you need our advice? You seem to have been able to do perfectly fine on your own before.
Oh, because once you date once at the age of 10, you know it all.
