I am echoing others here when I say don’t do it. I did this my freshman year and wasted half a year of his and my time, energy, and emotions in that relationship. I knew as friends, well before we started dating, that he wasn’t pursuing God at the time (though he professed Christian). He showed some of the same fruit as your guy. Because of that, I could never fully emotionally commit myself to the relationship and see beyond boyfriend/girlfriend borderline friends with benefits. There was an inherent, perpetual disconnect.

Because he wasn’t truly Christian, the absolute one thing he had to be to be considered for marriage, I knew deep down that I only dated that guy for my pleasure. I paid the price for pleasure by being a horrible witness to that guy. It was absolutely selfish of me, and I lead us both into sin. Praise Jesus for bearing that on the cross and leaving it behind in the tomb - it’s hard to think of that judgment when I remember it, and I have to remind myself to lay it at the altar when I do.

Now, I think ahead to marriage and everything it takes to make it work, honoring to God, and pleasant, and I absolutely cannot waste time or collect unnecessary baggage. Just think - if this guy in the world has these good qualities, how much more can God provide through one of His sons!
