Limerance or missing someone?

I’m trying to figure out whether this is limerence or just missing someone.

I spent a few days with a man. We had great conversations, shared interests, mutual attraction, and spent two nights together. He was kind, respectful and emotionally expressive when we said goodbye.

2 months later we still message occasionally, but we live very far apart and probably won’t see each other again anytime soon.

Yet I still find myself analyzing his messages, wondering if he thinks about me, and feeling attached to the memories.

How do you distinguish between genuinely missing someone and limerence fueled by distance, uncertainty and nostalgia?
