If it is truly God's will, it will be non-contradictory to His Word.
If he/she wants to sleep together before you are married (they justify it, see no wrong in it) they are not God's will for you.
God’s will is for you to be holy, so stay away from all sexual sin. 1 Thessalonians 4:3 Don’t you realize that those who do wrong will not inherit the Kingdom of God? Don’t fool yourselves. Those who indulge in sexual sin... 1 Corinthians 6:9a
Therefore, as God's chosen people, holy and dearly loved, clothe yourselves with
compassion kindness, humility gentleness and patience.
Colossians 3:12
What does being Spirit-filled look like? Letting the word of Christ richly dwell within you.

"But this is what I want to say—I pray you never, never, never yield to that temptation of the devil which would lead you to cry, 'God is dealing roughly with me! He will never save me!' No, expect quite the contrary! Because of these blows and strokes, because of your misery of heart, because of your troubled conscience, because of your inward distress you may all the more have hope! Nothing is more dreadful than to be without sensation—that is a token of death! But to be broken in pieces all asunder! To feel your thoughts to be like a case of knives cutting to the very center of your heart—this, at the very least, proves that life is still in you! Besides, remember that the path to joy is sorrow, the door to life is by death,"
You gave a wide place for my steps under me, and my feet did not slip.
-Psalm 18:36
He drew me up from the pit of destruction, out of the miry bog, and set my feet upon a rock, making my steps secure.
-Psalm 40:2
Thus says the Lord,
“Stand by the ways and see and ask for the ancient paths, where the good way is, and walk in it; and you will find rest for your souls.”
-Jeremiah 6:16
I encourage: step away from what is bringing you down–meaning bringing you down in the sense of what you know the Lord does not have for you (things clearly laid out in His Word for your edification and benefit). Don't go there. Step away. If He's said it, listen.
Beloved, He knows what is best.
What the Lord has for you is better.
