Well, if you have a good attitude about this, I would think it could be good to actually talk with her, at church or wherever you have opportunities to see her. Maybe first ask her if she is sharing with someone; and, if not, then say you would like to spend more time with her, but you appreciate however you do get to share with her.
But . . . actually . . . this is your relationship, not for me to rehearse it all with you!!!!!!!! I would trust God to have it go how He pleases, with no rehearsing and premeditating and controlling
But I do think that if she is a Christian person, she will help you, however. Treat her with trust about whatever she chooses.
When I got more friendly with my lady friend, I thought we were so comfortable together that she would readily accept my invitation for me to go see her on a Saturday. But she said she was not sure. I was surprised, but I said fine. And I trusted the Lord to decide and guide her.
Then . . . I think it was the next day - - - at church she passed me in her pick-up and smilingly said, did I want to meet her brother? ! ! !
And I already felt like I was with my wife . . . even for some time before then. So, I was enjoying and praying my way along. We have not gotten married, though, for a number of reasons, but we are possibly more one and comfortable than a number of people who are or have been married. The love is better than romance, even more intimate, I would say. God's love is better than any human experience, according to my experience and Psalm 63:3 >
"Because Your lovingkindness is better than life,
My lips shall praise You." (Psalm 63:3)
And what has helped is I hold myself to how Jesus says to love any and all people, not only ones who love us >
"if you love those who love you, what reward have you?" (in Matthew 5:46)
So, for some while before I discovered her, I have had this as a rule for how to love anyone special to me > also, Jesus expects me to fully love any and all others . . . however God has this work, of course. Be ready for love with each person . . . any person.
My commitment has been that I might get with someone very special for me, but we might not marry . . . but keep things moral, of course. But I am 76 years old. So, you're younger, not likely to want to be celibate with someone very good for you.
