Confused about breakup!!!

What does it mean when a guy breaks up with you and says its not you its him and he needs time to think about it? The thing is we’ve been going out almost 8 months and he has always been fully committed. We only get to see each other like once a month outside of school but just a couple of days ago he was talking about how he was going to call me everyday during the summer and it didnt matter if he only saw me 2 or 3 times. And how he never wanted to break up. Today was the last day of school. And he was perfectly fine at school. Then when I got home he called me and was like “I dont know if this is gonna work over the summer. I have to get a job and I dont know if I will have time for you. But its not you its me. And I still want to be friends” Thats what he said. And he said it might just be a break and would I take him back in a few months. Should I or not? Sorry if this does’nt make any sense, but I really need help and some answers!! I just feel so alone right now because for the past 8 months I talked to him on the phone all night and now its just like my life has just stopped!! And how could he dump me on the last day of school?? When I’ve been looking forward to summer and now its just completly ruined!!!
