Is it okay to like girls too much?

To a certain extent you should be fine. but excessive cravings over anything are a bad thing. You should try to keep everything in moderation and never to extremes. if you are talking about liking a single girl to much, its more or less debatable, some cons are that you could be taking her away from the rest of her friends, but some pros are that she will always have someone with her... just remember to keep it into moderation.
