Why does he call so much?

He definitely likes you. But calling that often can be a sign of someone who is controlling or manipulative, so watch out for that. The other possibility is that he believes you want him to call that often. If you do, then you may have a controlling or manipulative side, which you should put into check. If you don't, then you should tell him. Honesty is crucial to a successful relationship. Once a day is normal, twice is fine too. Three times is OK if there is something going on that warrants an increase in calls (like coordination for plans, your team won, you are having a hard time, he can't cook the dish you told him how to make, his mom dies, etc.). Four times is crossing to manipulative and maybe creepy unless there is an emergency or again, something big is going on. Five times...yikes.

He says that he just calls because wants to hear your pleasant voice, and calls three to five times a day, and you still have to ask if he has a crush on you? Isn't it obvious? Anyway, yeah, he likely has a crush on you, at bare minimum. Personally I think he's obsessed with you. I think you should ask him to just come out with it, but at the same time, I also totally get why you're annoyed. So when you do talk to him, tell him to calm the fuck down, and cool it a little, by calling less. A LOT less.

This is not something that will fix itself. You need to just come out with it and say it. It may be harsh, it may seem mean, but it needs to be done.

duh.. obviously. Three or four times are too much though..
