Does this guy like me?

Ok so there is this guy at my school and he is really sweet. We have known each other for now six years and we have been best friends. Lately he has been sitting next to me every single day on the bus and we talk the whole time. I think its been six days now, we have been texting all the time. These conversations can last hours and we NEVER run out of things to talk about. Usually he texts me first but sometimes ill tell him that i am busy so i will text him later. One day when it was a half day at school he invited me to go to taco bell (with other people but he didn't invite the other people.) When we were at taco bell we sat at the same table and talked. When we are with each other we laugh and smile a lot. Finally, we say good night to each other every night before we stop texting. So does he like me? And sorry this was so long.
