Hm, Quadro and I are both pretty damned mushy. We try not to be so much so around other people, but we say it pretty frequently. Mostly cause I just can't help it, I want to!! Plus, we are aware that both of us have some needs that way... we both need some re-affirmation. While neither ever doubts the other's love... it's just life that gets to you sometimes, and if your SO just calls and says "hey, i love you"... it makes me feel a bit better about how the day is going. I think Q feels the same way. It's not just "hey you're special", it's also "hey you're special, and the day is going to get better".
Were it me in your shoes, I would feel that your BF should be able to tell you a little more often - once a day isn't so much, really - and you should shift a little too, to being okay with something like once a day. Compromise... ah, the cornerstone of most relationships!!
