Boyfriend issues

So me and my boyfriend have been together for 4 and a half years. Which I feel has mostly been good of course everyone has issues now and then but last week he drops the bomb that his is confused and not sure if he wants to still be in a relationship and doesn't know what he wants and not sure if he sees a future together anymore. Definitely didn't see it coming. So after a long weekend last weekend trying to decide what he wants to do. He could not give me a answer on if he wants to give it a try or go our separate ways. So I didn't want to keep on fighting for us if he didn't so I said it was over and I would move out but everytime I did ( this happened twice) he wasor no let's try. So here we are a week later and I feel like we had a good week together. My problem is that I can't get out of my own head which is so dumb I am a overthinking so as soon as he acts a little different or anything I overthinking it. I have anxiety issues and overthinking everything. I am breaking my own heart by overthinking his every move and every action. I am trying to work things out and I feel like most days he is and others not so much but again I could just be overthinking it😉. So I am trying to rekindle this relationship to what once was. It sucks because we can't really go out and do much because of COVID-19 plus he hurt his knee and is waiting on a MRI and maybe surgery. Which I think is part of his issue because he is currently not working and doesn't know until next week what is happening. So over last week he said he doesn't want to drag me down and drain my savings in case things don't work out and he doesn't want me to spend my savings on him. So yeah unfortunately we can't enough go out and do much because of his knee and saving money of course. So of course I overthinking his every more and action. I am just afraid he is going to decide he doesn't want this and I get hurt all over again or he gets bad news next week with his knee and breaks it off because he doesn't want to drag me down. Even though I told him I was in it for the long haul. Sorry guys that was long. Help
