Is saying "love ya" less meaningful then I love you?

My boyfriend told me he loved me first, we had been together for 4 months, its only been a few weeks since and now he says love ya. I know he loves me, but it just seems so much more impersonal. He rarely says it to me either, actually only has 2 times since the first time he says it. But he doesn't say it through text before bed, but as I said he says love ya. Is it maybe because he just isn't all the comfortable yet? If it makes a difference, we are both 27 :)

I meant he DOES says it in text before he goes to bed. He has only said it in person a few times since the first time he said it to me. :)
