Should I stay with my fiance (advice preferably from Christian couples especially if married)?

I am engaged and I believe in Christ and my fiance says he does too. I have had my faith for many years but for him although he says he believes he admittedly has not really established a foundation per se in God. I am finding it disheartening that we don't regularly pray together. I feel like he will move on in conversation when I talk with him about God or share things with him I have read. I fear that my desire to do this is not his desire and that this could cause minor riffs. I don't want to feel like I can talk about God or pray with others Christians but not my fiance'/future husband. He said when we met he wanted this spiritual woman and so when he met me he says I was what he was looking for. But when I am talking on a spiritual level with him his response does not appear one that wants to talk about this. We recently spoke about this and he said he just is not motivated. I asked him about fellowshipping with other believers- he doesn't really do this except for when he goes to church with me. I don't want to feel judegemental or like I am pressuring him. I have felt concerned by this and wondered if as a couple looking to marry should I reconsider. Should I just wait to find someone who is on the same page because they want to be and not because I am asking them to be etc. Please only offer sound Christian advice
