The idea that God has someone special just for you and is going to make you both meet and you are supposed to know that they are the one is not in the bible.
It might be an easy to accept concept because we know that God is all knowing and so we deduce the rest from that.
Or some might get the idea from reading about Abrahams servent being lead to Rebekah after he puts out a fleece. However that story is specifically about being directed to a relative that would fulfil the servants orders and the objective of maintaining a Hebrew lineage. Not meant to teach that God has a special someone just for you.
Paul's teachings on remaining in the state you are called to the Corinthians due to the persecution and stress they were under and which was about to get worse demonstrates that marriage is a choice.
You can choose to marry the person based on common sense. If they have an anger issue, walk away, they are NOT THE ONE and God is not telling you to make a stupid choice.
If they seem perfect in every way but you really enjoy your freedom and alone time, you can walk away and stay celibate and alone. You did not turn down THE ONE GOD CHOSE for you. That is not how it works. If it were Paul would not have said what he said in 1 Cor 7.
Also,.... Princesses in history were historically very bad people. They willfully and knowingly were cruel to the peasants that they ruled over and took what they wanted from them to support their lavish lifestyles. So enough of the fairytales people. You are not a princess (and you really would not want to be if you knew the real ones) and there is no Knight in Shining armor (they were a murderous lot) coming to whisk you away and make you live in a castle and be happy ever after.
And there is not just ONE made JUST for you looking at the same moon you are tonight!
You get to choose. Choose wisely. If there are red flags do not ignore them, they will only become major problems later after you tie the knot.
If your potential person clicks their teeth with their spoon when they eat their cereal and this bothers you, and you plan to teach them how to eat with a spoon without making that noise, later after you get married, you should not go through with it. That person will resent you trying to change them and you will also find a billion other things that bother you. If you cant ignore things now do not plan to change them later.
I have more advice but I will wait until I see how this post is received. I am not going to waste my best advice on a hostile audience.
