Just because he/she never said he/she liked you, it doesn't mean that you can't read the signs he/she likes you more than a friend. It is common for men/women to try to hide such things because they think they will make them more vulnerable and they want to know you like them back before they make the first move. Here are some signs showing features of him/her being more than just a friend.
You talk to her/him every day on phone
Talking to each other on phone becomes a daily ritual. And you don't regret that! This is one sign that you're getting comfortable with a friend.
He/she makes you a priority
A person who is in love with you will make you a priority in his life. This doesn't mean he doesn't care about other things and people in his life, this shows that you matter to him/his and he/she wants you to know that.
There's also the fact that he notices the little things about you. The new haircut, new shoes, or the fact that you've recently changed shampoos. Maybe it's the way you smile depending on the circumstance. Either way, he notices and likes it.
You are protective about her/him
You feel as if it is your duty to protect her/him. This is one sign that she/he is more than just a friend to you.
He/She touches you
Accidentally, or just subconsciously, he/she makes some kind of physical contact with you.
You share all your secrets
As the proximity increases, you tend to reveal your secrets to her/him without thinking twice.
He/She gives you a nickname
This is just another way of him trying to tease you. If he/she tries to give you a cute nickname, or any nickname that's supposed to tease you, that's another great sign.
He/She hangs out with your friends
Everyone has that annoying friend, and nine times out of ten, it happens to be your best friend. He/she doesn't like her/him, but he/she'll hang out with her/her because you are there. That's love.
You go out for lunch together
Having lunch together becomes a regular thing and you treasure all those moments.
