Is love instant?

I’ve been dating this guy for a couple of months now and I do really like him and he treats me amazingly but it just feels like there’s maybe something missing, with my daughters dad instantly I knew I loved him, I wanted to spend all my time with him and when I thought about him my heart would just burst but with this guy I like him a lot, I enjoy his company but I could happily not text him all day or only see him once a week, I know I don’t love him but I don’t know if that’s yet or I never will? I’ve only dated a few people so I don’t know if this is normal
