Friends after break up?

Today I was thinking can you be friends with someone after you broke up with them? Andddd I'm not sure.
While I was in relationship he told me that he wanted to stay friends even after we broke up and I agreed,but when I broke up with him a month later,we never talked again...I gave him space,I didn't want to push it.
I know it's shitty to ask someone to be your friend after you broke up with them even if they said they wanted to while you were still together so I didn't do it. It was probably hard time for him and I didn't even expect it,but after some time and summer break I guess he should be over it or he maybe hates me now?
I really don't know,he even tried to make me jealous but I wasn't jealous at that girl,his plan didn't work so I guess that made him kinda angry? Maybe he doesn't hate me,maybe he hates the fact that we're not together anymore and that our relationship wasn't so special..I don't want to be in a relationship with him,but I miss being friends.
What do you think can two people be friends after break up?

"Material World"

So today in school we had to write about 10-15 sentences and the title should be "Material World". Some of us didn't know how to start so teacher tried to explain. This was in religion class so teacher said that we should wrote about how some people cared about money and their appearance a little too much and on the other side how some people didn't care that much and cared about God more. She also said that the things material people did were usually sins.

I don't agree with her at all. I think that there are people who aren't material but that doesn't mean they have to believe in God. And material people can believe in God too,but also be obsessed about how they look, how much money do they have and what other people think of them. I didn't like how she put it that way that you can either be material or believe in God. What about people that are neither? Do they exist? I think so..what do you think?

First Day of School/Random thoughts

So today was the first day of school :)
I'm feeling so tired :( I woke up at 6am,but that's super early for me and I stayed up late.
I always do that,stay up really late and feel really tired all day..
Anyway,I think that you got it by now that it was a shitty day for me haha
It feels so weird to be back in school...I'm not stressed about school yet,but some people are already on my nerves..but still nothing changed haha I watched 3 seasons of awkward. in 2 days :)
It feels so weird to see people again you used to talk to but now they don't even say hi..
I ate pizza today,so that's all that's been good today :)
There are not a lot of things that can cheer me up,but music always makes me feel better :)
I'm really worried about this girl in my class,we're really good friends and lately she got really skinny,she lost 12kg and she still thinks she is fat..she wasn't even fat before losing 12kg. I tried to tell her that she is the perfect the way she looks,but she isn't listening to me..any advice?
I wanted to write more but I gotta go,sorry
