Is this weird?

Whenever my boyfriend and me finish our phone conversation (he calls me everyday while he's at work) he never says "I love you" before hanging up with me. He will just say bye and will only say I love you after I have said it. He tells me he loves me when he's with me tho but it never feels romantic to me. He also goes to bed before me and never says goodnight or I love you. He just silently goes to the bedroom. Is that as weird to you as it is to me?
