I need advice

I need advice on advice my friend is asking for lol. Him and his girlfriend are having problems and he's not sure if he's ready to fully commit. I mean they are young, 17&18 but she's moving fast for him such as talking about marriage and their future after 9 months of dating. And he says this "turns him off" I'm trying to be helpful, he says he really loves her and would love to marry her one day. 
So how would I respond to this message ? 
"Yes I do feel pressured . I can't build our bond naturally its forced and I want to do it naturally "
