Wondering About a Marriage When Faith Levels Differ - Need Advice

Assalamu alaikum, everyone. I'm reaching out because I'm in a confusing situation and could really use some perspective from a Muslim viewpoint. I was raised in a very religious household, and having a family built on strong Islamic principles is incredibly important to me. The person I've been seeing for about a year and a half is, in every other way, an amazing match. His character is excellent-he's respectful, has great morals, treats me wonderfully, and has even stopped certain habits that weren't compatible with our values for my sake. Here's where I'm struggling. While he is respectful of my faith and has even participated in acts of worship like fasting during Ramadan, he doesn't yet have a firm, personal belief in Allah. He's expressed that our meeting feels like a sign to him, and he's open to the possibility of developing his faith, even promising to fulfill religious duties. But his belief isn't rooted in conviction yet; it feels more like he's doing it for me. My heart is torn. On one hand, I see a wonderful, supportive potential husband. On the other, my dream has always been to build a home where faith is the foundation. I'm worried about the future and raising children in a household where our levels of iman are so different. Has anyone been through something similar or have any advice on navigating this? JazakAllah khair for listening.
