Bf of five years wants to be done!?

It’s been a ROUGH past month for us. We initially took a break that lasted about 3 weeks. During that break, my anxiety, stress, and depression got worse. So when we were done with the break I sort of pushed him away because I didn’t want that to impact him. So I wasn’t going over as much, I wasn’t texting as much, etc. today, I asked him what’s wrong because he was very distant. He told me he just feels it less and less now and he wants to be done. I explained to him everything but he still says he’s pretty sure. I told him it’s most likely because I pushed myself away and that’s why he’s feeling it less because I literally haven’t been around. I’m spending the night tonight at his place but I’m scared of what’ll come tomorrow? Idk what to do??
