Guy won't stop messaging me?

[kate]

So there's been someone who I've been talking to over Facebook a lot recently. We talk pretty much every day, and we chat when we see each other at school. I really like him (as a friend) but the thing is, sometimes I just don't feel like talking to him every single day as neither of us are very good at keeping up a conversation and it can seem a bit like hard work sometimes. He's on Facebook 24/7 so whenever I log on, he messages me straight away! It feels like I can't escape (I know that sounds horrible!)

I do want to become better friends with him, but I'd much rather talk in person at school rather than over Facebook. Is there any way to tell him this without being blunt and saying "leave me alone!!" ?

Thanks a lot
