Does he like me?

UPDATE: so neither me or him have said anything about dating. But he did literally say he wanted to take me somewhere! Also he called me pretty and said that he wishes he could see me more. (Because I'm homeschooled and he isn't) I am really thinking that he likes me back!!!

Ok... so I have a friend who is a guy and I really like him! He is extremely nice to me.. but he isn't very nice to anyone else. He is the only one of my friends that knows everything about my illnesses and he texts me every night and just asks me how my day was then we end up talking until like 2 in the morning. He offers to stand up for me when it comes to some of my other "friends". He is somewhat flirty at times but that is it. Would you think he likes me or not??
