Most Helpful Guy
Hello, in order to help you I must be a bit more direct, so you can really know what some men think. Try not to take this personally.
Add him and tell him you like him as more than a friend. You MUST indicate you like him as more than a friend if you want to date him. If you don't he will move on. Most men have enough friends and what they want is a date. Men will not pursue girls if they don't escalate to indicate the girl wants a date too. And most men won't want to date a girl who can't even indicate she likes him as more than a friend. A relationship requires more confidence than that.
If you are too shy to ask him out when you are ready, this line worked on me. From her to me: "So, when are you going to ask me out?" That makes it plain she wants to go on a date. :)
