Non Believing Boyfriend

My boyfriend for the past 5 years and I have recently been talking about getting engaged soon and relocating so we can be back in the same city together. I really feel this is the person for me and I absolutely love him but he isn’t a believer. This has been an issue our entire relationship that he would like to believe in God but just doesn’t. If anyone has any advice on how to handle this or how to help him find Jesus I would really appreciate it.
