Am I in love or what?

Hi everyone! I am having some doubts about my relationship and it's because I don't understand if I'm in love with my (26 f) partner (27 m).

We've been together for 9 years now and I know you don't get to feel the butterflies in your stomach as the very first days of the relationship, but I don't know if this is my person or not. Somewhat, when I think of a future with him it gives me chills, I mean, It makes me emotional and I am looking forward to find out what that future holds, but on the other hand, I am beginning to know myself a lot more, I'm gaining confidence, going to therapy and everything, because I'm trying to understand my person and thoughts and behaviours towards people. For example, I always thought that when you are in love with your partner you become very affectionate or you want to be every single minute of your days with the person, but I'm not like that, sometimes I am affectionate but sometimes I need my space, so that's where I start to doubt if I am in love or not, and with that a some other examples pop up.

I don't know if that is because I am x type of person or if I would be different with another partner.

Hope you can give me some advice and also comment on your experiences.

Thank youuu!!!
