How to not feel boring around my boyfriend?

[Emma]

We were really good friends for months, but now we've taken our relationship to the next level, conversation is always drying up and I feel as if I bore him - in the holidays we hardly see each other so we chat over Facebook like everyday, but he takes ages to reply and its always about boring stuff like how our day was - I never know what to say back... it would be better if it was more interesting? But how? I need some advice! Thank-you! (And I will remember to give 10 points for the best answer this time!)
