It really depends.
I had a 4 year relationship with a man I remain friends with, who never said it. We were living together and co-parenting. He had personal issues with it.
I honestly opted not to concern myself with words.
On the otyer hand-I say it and said it as I wished. He was free to not respond. But he was not free to tell me I could not say how I feel.
