My Muslim boyfriend wants me to convert, but I’m an atheist. How do I navigate this?

I (21F) have been dating a Muslim guy for a while, and he recently told me that he wants to be with someone who is ready to convert. He said his parents would be happy that way. I respect his beliefs, but I am an atheist and have no desire to change that.

The thing is, I really like him. This is the safest I have felt in a long time, and emotionally, this relationship has been good for me. But now, I feel like I’m at a crossroads. I don’t want to lead him on or compromise who I am, but I also don’t want to lose what we have.

I’m not sure how to approach this. Has anyone been in a similar situation? How did you handle it? Any advice would be appreciated.

Edit: Hey everyone, thank you for your insights and opinions. Honestly, some of them even brought me to tears. This is a difficult time, and it's hard to compare/measure this one moment with other amazing memories. But I’m clear now it’s not going to work out. Again, thank you all!
