[Face Up.]

I'm sorry that you are going through this! It's definitely a lot.

Do you think it would help to talk with this friend in a quiet area when neither of you have heightened emotions? You can explain your side of things, but also allow him to explain what's going on from his point of view as well. If things start to go south, it's okay to pause the conversation for a while until both of you are in a better headspace. At least that way both of you will be on the same page.

If you don't think talking to him would work or it doesn't go well, I think it might be necessary to take some space. You're working on the project together so you can't avoid him completely, but maybe try to only communicate with him enough to get the project done, and not talk about things unrelated to the project. If he won't communicate with you to at least get the project done, you might need to talk to the teacher so you're not stuck doing the entire project by yourself.
