Someone talk to me about this 🤧

My crush of 4 years has finally asked to hang out... the movies to be specific. But I’m so confused and honestly a bit scared because he rejected/ friend-zoned me. It started when he was a freshman and I was a sophomore. He found out my junior year and my world came crashing down on me. Lol 😶😂 (I hate my life) immediately after that he got a girlfriend. At a point he said I wasn’t in the friend zone and that we just don’t hang out outside of school but he wouldn’t mind getting to know me. His girlfriend cheated on him so they broke up but are still friends. But fast forward, he’s about to graduate and I haven’t seen him or spoke to him fr in almost a year... one day he hits me up and asks me if I wanted to go to the movies with him. Unfortunately I was busy so I asked for another time maybe. And he said sure and when would I be free. My question after all that, sorry... is why would he ask to go to the movies now?! I’m honestly confused. We’re friends and he’s not a f boy or anything like that. Im a virgin and I don’t think he’d just want sex, I just need to know his angle
