@sheema,
Don't mistake respect or care for love. He may be there for you, pay attention, and be patient with your tantrums because he's being a true friend. That's what friends do regardless of gender; however, if you really think he loves you, why don't you just ask him? No one can be 100% sure but him. All anyone can do is speculate. It doesn't have to be awkward. If you're really that close, no topic should be off limits, and you should be honest with each other. It's a lot simpler when you are communicative. If you are too afraid to ask, why don't you make a move? If he responds, then he is into you.
