Can anyone help me ? (boy advice)?

Me and my boyfriend broke up a few weeks ago. We were dating for a year and seven months. I'm a junior and he is a senior. He got worried and started thinking bout the future and got worried that we might not work out. We broke up 2 times before, once was for a few days and another was for two months. Since then he has been doin some things, like asking me to wear the ring he bought me and other stuff, which seemed obv that he might want me back. I confronted him monday &he said as of now he jus wants to be friends and he doesn't wanna fix things. He says I'm a close friend and he really cares bout me and that if he wants too fix things he will and he will try "soooo hard". He said sorry if I felt led on. I've decided to jus let him go unless he decides he wants me back. Since that day, I've brushed him off and yet he IMs me when he gets the chance and if I walk past him in school, he calls me over and doesn't let me ignore him. During other break ups, we barely spoke..we would just walk past each other and if we did speak..it was kinda awkward, and we were both having mixed feelings. This time feels different and weird. Idk if he is doing this cause he wants to be friendly with me or cause he wants us to work out later on in the future. Still, ppl see us together and sometimes think we r still going out or he tries to get me back. And as of now, I know he seems confused lol
