You shouldn't do anything the fact you question this is not because you think he is jumping into soon, it sounds like he is secure, you need to look at yourself and wonder... well if he can say it, why can't I? Do I have an aversion to it? Is he not the right one? You need to figure this out quick or he may just move on

It doesn't sound like 'too soon' to me, he's known you for 6 months that's a fairly long time. Maybe as you grow older you you don't just say "I love you" in a couple of months- I don't know.
Everything that he's done sounds sweet- but it does seem like too much in just a space of two months.
