Am I falling out of love or has the honeymoon phase just ended??

we’ve been together for 8 months.

I all of a sudden saw him as very “meh.”

I am bored, which made me panic.

We don’t really talk that much anymore.

I don’t feel the butterflies I felt before.

I still get upset when I think about him with anyone else.

I don’t really want to have sex.

I see him as my family.

I’m very confused, I’ve never felt this way before but I just feel safe and trusting around him.
