Don't ever ask a girl what she likes in a man. They will say "oh I like flowers and etc". They like receiving flowers, that's right. But they don't feel attraction for the guy who gives them flowers (unless they are in a relationship).

No. Don't do it this week. Do it the next week, but not alone. Invite some friends (including female friends. Say for example 5 friends and if she comes she can even be your bowling partner, but only if she has skill!) and tell her "hey I'm going with some friends bowling, join us".
