How do I deal?!

So my boyfriend and I have been together for just shy of a year. Our relationship was the stuff of movies, like full blown head over heels just every relationships dream, except I struggle with mental health issues like anxiety and o have some patience and anger problems but as does he. At the beginning of the relationship my mental health got in the way but after a few fights I realized I need to change my ways and do my best. I’ve gotten so much better than at the beginning and I’m proud of myself but I slip up, as will anyone. But when I slip you getin my own mood that I don’t get out of for alitte while but once I do I apologize and I fix what went wrong. Well I slipped up this weekend and he did as he does and flipped out on me, I understand cause I’d be mad at me too, but when he gets mad he gets mean and all these mean things he barries comes out and he’s just mean and vicious and he says all these things that he’s kept in and he finally decided to end it, I obviously begged like hey I’m doing better please be patient but I’ve been “killing him inside “ and he’s no longer happy he says he needs to lie to keep me happy and etc, which any girl on here can vouch for lying being the worst and he always assumed for me how I’d react to things and then he’d be mad about it. He constantly assumed my feelings and actions and never ever spoke up about being unhappy or about how we need to make changes, he never gave me a fighting chance. He then proceeded to say that he was afraid that I’d be a bad mom because I don’t have an amazing job and he was worried he’d be the only bread maker for life and he wants our kids to be well off, that I’d be anxious forever and ruin everything and that I’d never learn to drive, he said all this not knowing I have been applying to larger jobs for months, just ordered CBD oil and have been doing homework on my mental health and looking into my drivers but I thought I’d just take my life one step at a time and not overwhelm myself. He was impatient and assumed. I love this man more than I’ve loved anything in the world and I’d do so much and I am doing so much to be better I just wish he’d see I’m not the only one that needs time to change. But he’s adamant on needing space and time and that’s so scary to me what if he doesn’t need me around?! I want him to miss me, I want him to realize what’s here. He leaves for Europe on Friday for 10 days and I wish we could get this sorted before then so that it’s not worse for us but I don’t want to rush it.its so hard notspeaking but I feel like I should leave him alone. We said we’d talk Thursday. What should I do? How should I act?! I know he loves me I know he really does but I feel like he’s taking it too far instead of us just working on things.
