It's the awkwardness that may remain afterwards that concerns me.
Thank you for sharing such a personal thing with us.
You trust God about whether or not you will feel awkward. And my opinion is He will not have you feeling awkward if you two gave your relationship to Him and you honored His choice.
If He rules that you are not for each other, He means this for your good, nothing to be ashamed or awkward about. So, it is good to pray and prepare so you will be pleased and even feel honored, whatever is His will. And you will be able to more deeply trust her, if both of you are truly honorable and God rules for you not to marry > you both will know you honored God, and you will reap from this.
And while you pray with each other and receive support from others who are not prejudiced about you, but support you in making sure with God in prayer . . . this will help to build you and your church in relating and in making sure with God about His will. And then, in case He has others for you two to marry, you will have valuable experience you can use to help you for discovering who you belong with. Plus, you will be able to use this as a testimony for helping and counseling others.
So, there would be no reason to feel awkward, if you have honored God so.
In any case, make sure with God.
"Test all things; hold fast what is good." (1 Thessalonians 5:21)
This includes making sure about who you listen to. "Well-meaning" and "wishful" people can be hasty to feel it would be so nice for two nice people to get married. But this can backfire. And there can be people who "hear from God" that you belong with each other; but not all people are reliable when it comes to hearing from God. So, make sure with God about who you listen to!
Make sure with God about "all things"; this way, you grow in being good at this, for the big things
"'He who is faithful in what is least is faithful also in much; and he who is unjust in what is least is unjust also in much.'" (Luke 16:10)
So, my advice is that you two make sure with God about even the little things; be faithful to make sure with Him about what is "least", and this can help us to develop and mature so we are good at making sure with God about much bigger matters. And my experience is that when we give God even little things, He does great things with our supposedly unimportant things.
If you have a brick house, that house is a big thing. But one brick so small can be quite important > I mean, if one brick is missing from the wall of your house. Little things can be actually quite important . . . building blocks, even, for what is greater. So, it is good to be good at testing to make sure with God, all the time.
And as we get good at this, we get more confident and creative with God . . . not awkward!
And we do this for others. God is all-loving; so how He guides us will have His all-loving good for others, too. In little things or in being a married couple, what you do with God will be good for you and minister His grace also to others. So, part of what He might have you evaluate is if and how well your relationship now is already ministering to others to help us all grow and learn how to relate as brothers and sisters; and while you are learning from Jesus, right now you can be helping others, also, to evaluate for and even prepare for marriage. As you get grace for this, minister this >
"As each one has received a gift, minister it to one another, as good stewards of the manifold grace of God." (1 Peter 4:10)
