I’m still infatuated with my ex but I don’t want to date them

We broke up 3 years ago but I still crave their presence. When I’m around them I feel as peace and I feel seen. Their hugs make me feel like the only person in the world. But I know that we can’t ever be what we used to be. Not because of them but because of me. I love their presence and compassion but I don’t want a relationship with them….but idk I’m ready for them to get into another relationship.
