Is it normal to still mourn and cry after my dad died 30 years ago?

My dad was my soulmate. He was wise, funny, empathetic, kind, understanding..... can think of 100 more words to add. I have frequent dreams about him and whenever I talk about him, I cry. Tears are rolling down my face as I'm typing this. I miss him so damn much, not a day goes by that I don't think about him. Is this normal?
