I got (10) ''likes'' with shopkeeper, now when i help him dont up anymore, i missed something ?
You have to start doing other things to get him to like you, now. Usually after that many you'll have the option to join him on Friday evening's for hunting in the woods at his friend's cabin. I think that adds 2 each time. After you get like 20 (I think) you get a heart symbol, and he'll invite you to join him in the Hot Springs on Saturdays and/or Sundays after work.
Helping him only works for a certain amount of time.
You can gain some points by doing the quest "Lost friend", also if you didn't took the payment for medicine when you cure him from his sickness it also makes him like you more. You can meet with him in the bar if he likes you enough, that's a start of the romance route.
Like red1979 said, at some point you can talk about hunting evening. If you make everything right there then you are going to get a heart and that unlocks the Hot Spring date.
make sure you've exhausted all of the talk options too, there may also be other requirements (make sure you exhaust all talk options for all characters, esp the bartender for hints)
[edit] even talk options that don't have the question mark next to them can change/result in affection increases after revisiting them, so be sure to do so after every major event (especially the "ask if you can help" option for Bernard, the outcome of which can change depending on your character's STR)
