I think you did a fine job. You both had fun. Now you are rolling the dice on whether you are going to see each other again. You putting your money all on one number which is a bad idea. You may have to think about if you lose all that money what would be the result. I think you put a little money on the number and if it returns anything its a good gamble if not you have money else where, as they call it edging your bets. Dont invest too much in one girl just because you had fun that night. There are loads of other girls who does that ever night.
