I don't know the answer to this question. If what you're doing is not sin then there is a point where two people coming together is no longer fornication outside of marriage, otherwise it is always sin even if two people are together for 40 years, in love with each other and God and faithful to each other.
Those are the two possibilities.
I know that when I was living with my partner outside of marriage, I was coming from a place of impatience. I was trying to fill a void using her, and not using God to fill that place. I ended up being quite harsh with her and not spending time with her, just demanding and telling her to get out of my hair, and she took off to live with some guy she met on the internet.
I was heartbroken, and she ended up worse. I "loved her" for what I could get out of her. Not from a place of giving myself to her and treating her with the dignity that God values her at. I still pray for her, and feel a weight of responsibility for where she is now. That's just a testimony of my experience with living someone before marriage.
I wouldn't say that God is ever distant. I believe that Jesus has forever abolished the separation between man and God and the ability our sins have to keep Him from loving us. It's just that coming from a place of it being about you, and satisfying yourself, is detrimental.
Yes, you're still accepted.
I don't know if it's sin, most Christians would say it is.
