That was my first thought about the jobs as well. I know it's tough to see anything outside of how terrible you feel that your beloved is hurting, but try to take a step back. If he is BPD, the odds are very high that he's manufacturing all these crises or bringing them on himself. You can't rescue him from himself, and you'll just wear yourself out trying.
There are a lot of tools you'll learn about here for those times when it feels like you can't do anything right. I would start out by trying to validate his feelings of sadness etc and don't engage in any arguments about what you supposedly did wrong. If that isn't enough to keep him from attacking you, you might need to use some boundaries to take yourself out of the line of fire. I know it feels cruel to (for example) hang up on him when he's clearly suffering so much, but in the long run it's the best thing you can do for both of you. He needs to learn how to handle his emotions without lashing out at you, and you don't deserve to feel like everything you do is wrong.
Please stick around here -- we've all been where you are and there are ways to make it easier on you
