Bf being an idiot because he’s burnt out

Feeling crazy rn. 1yr 5m relationship me f30, him m27. I literally was chatting with my grandma this weekend about how great things are and how hard my bf is working to hit his financial goals and grow his nest egg from the ground up so he can have more security. He's been pretty much scraping by for a while but he got a new job with unlimited time and a half OT so he's working long hours that often get him going home after midnight and 6 days a week all so he can make up the cash to cover bills and also start saving. Yay for him! He's been a real rockstar about it. Given his schedule we have been seeing each other roughly every other weekend with his one day off. It's been me and him asking pretty equally lately. So here's the kicker. He's been a little distant the last week or so and I know he's working hard and stressed and he has a history of depression so he gets like that sometimes but after I probed him yesterday about not having anything to say at all the last two days he comes out saying he's ending things??? He said with his finances and schedule he can't be in a relationship. He was being very dramatic saying I said something and he couldn't look at me the same but then just said I was talking about "us and we time" when he doesn't even have "me" time. We are going to chat on Saturday when he has his day off over here at my place so I'll get the full details on what he's thinking but he said he made his decision already and I was just so mad about it after we finished our texts. I said I'd leave him alone for the next few days since I know he's got a lot on his plate and we already have the weekend to talk it out but I'm really over here like wtf? I feel like things are going great we already had a talk about wanting to make this work between the two of us and everything back months ago and I totally validate his feels about being overworked and not having time but I don't remember the last time he turned me down for a hang out and like I said he has been asking me out more lately since he's got money again. He was saying how happy he was that he can start to spoil me like he always wants to do but hasn't had the money for most of the relationship. And it's been nothing extravagant we go to like the movies and for cheap sushi dates and stuff. We have no problem splitting checks or one or the other picking up the tab and just swapping. He has not said anything lately about needing more space or anything. I'm totally happy to negotiate what the relationship looks like. We've done that every step of the way basically. I'm just so flabbergasted by the situation. Usually I go straight to sad in situations but this with our history and finally having felt secure in a relationship I'm mad because I feel like he's just being an idiot and insecure and pulling out instead of just talking about this stuff. Ugh we've both come so far in this relationship and grown a lot because of each other healed a lot of wounds from other people all the really good stuff and we are each others cheerleaders. Anyway I guess we'll see what he has to say on Saturday. I'm just trying to stay sane for the next few days and not spiral into overthinking too much in the meantime. I'll take any advice on how to talk to him. I really think this is a simple fix for us that doesn't need to end in a break up. I'm even planning to ask him if he wants to just take a little break from each other so he can focus on his stuff for a little while. Like relationships ebb and flow and I can entertain myself while he's doing his grinding. We text mostly all day so I can understand when he doesn't have the energy for it to keep up and stuff. But just because we don't talk every second doesn't mean we're going to stop loving each other. They say distance makes the heart grow fonder after all. The last time he tried to split things up last year it was pretty much the same deal and we did come back even stronger after having a measured break. So my headspace is in disbelief of him and I don't think he's working in his best interest by trying to end things and just feeling like we just need to talk things over and have a little breathing room or something. I know he's obsessed with me and we love each other endlessly. He even said "I wish things were different" lol like it's our relationship and we can make it whatever we need it to be. Anyway sorry this is so rambly. Comments to keep me company while I wait are much appreciated haha 😂 wish us luck this weekend!
