well unfortunately each bloke is different but due to the hole in his pocket the roses and chocs would of cost i think it was more than just a gesture. and of course the best friend asking you a question like that which clearly they both think 'isn't too obvious' yet clearly is, shows a lot! well i would say dating at most currently most blokes are stereotypically scared of commitment so i would hold off asking aswell. They like to feel they are in control and no one has pushed them into anything. I say hold in there and continue as you are as it seems to be working x
