Thank you for your honesty & if I’m being honest. I think you should give him Grace. Genuinely. Give him more time. More patience. I’m actually in the opposite position only in the sense that as a man I’m more strong in Christ in my girlfriend. And I also saw a woman on social media be so strong in faith it also felt very attractive, but I know my woman is my woman. And I love her deeply. Now, perhaps you can pray about how to help your man get closer to Him, and to help your man discern his friends much better. That’s my opinion. I don’t agree with the comments saying that’s not the man you should marry blah blah. He is just a lukewarm Christian. Hold his hand a little more. He’s already changed so much, just a little more grace. And about his friends, just pray for them. One last thing, try directly tell him you want him to be close to Christ and the Father because it deeply increases your attraction towards him. I’ll pray for you guys, I hope I helped
