Is it for love or comfortability ?

My husband and I have been together for 2 years . Married a year . Friendship for 10 years, he was my first kiss. I know i love him. But are we together for being in love or are we just comfortable with each other? How can I tell how he feels about me without asking? Help me

Edit: we have 4 kids. My 5yo . My 2 yo. Our 1yo ( in heaven) and I’m 22 weeks. .
