My partner thinks I am a bad person

I've been with my partner for 4 years, the first two years were a disaster. I had a mental health crisis and suffered with severe BPD episodes, I was genuinely a bad person then or maybe just a very mentally unwell 15 year old.

Despite this, they got back with me after a couple breakups.

We have ups and downs as every couple but it always repeats the same patterns, we are all good for 1-2 weeks then we have an arguement and then the rest of that week is bad with arguements and resentment etc.

I understand why they resent me, considering my behaviour at the beginning of the relationship but equally I don't think me being that mentally unwell defines how I am now at 20 years old. I'm back in therapy and I'm trying to do better everyday.

But when we get into arguements they tell me the same things everytime, that I am a bad person, that I never listen to them, I don't care, I will always be like this, I'm useless, I'm stupid and delusional etc.

It's really hard because every arguement seems to be about what I am doing wrong, even if they have done wrong to start.

For example, on Sunday I asked them to take the rubbish out to the bin meanwhile I put my headphones on to do some washing up. I didn't hear them call up the stairs multiple times because of that, so they came back upstairs pissed off and asked what bin goes out, I said "the black one". Off they went back downstairs and took the bin out to the curb, I didn't realise I had told them to take it out out, i thought they were asking because Monday is the day you take the bins out so I figured they were asking to prepare for that. They came back in and I realise my mistake, I had told them to take out the bin. I said "oh, it's Monday to take the bins out, you didn't have to take it out today" they got audibly annoyed and very angry, said I had embarrassed them infront of the whole street and called me useless etc. I told them they should not speak to me like that, I didn't realise and it was a mistake. They got angrier and angrier and the whole day was a disaster, it was hot and they were in pain.

This is most of the arguements, I will do something wrong, they get angry at me but at the end I end up apologising because I 'started it', maybe if I just listened etc.

It annoys me that they never see how they contribute to the problem and it always lands on me, it does make me pretty resentful because I feel like I'm being constantly blamed and then get a mad partner too.

I can be rude and angry, I'm autistic, my tone is often 'off' or inappropriate for the situation, they've known I was autistic our whole relationship. I do try and control my tone when I recognise it but often it seems like I am being rude or sound rude/angry when I definitely am not. It's nothing personal to them, but it really upsets them and honestly I don't know how to fix that. They like to remind me ill always be like this and that I'm just a bad person, and I'm starting to believe them.

I'm not entirely sure what to do anymore, there's deeper things than this but this has been my last 2 days.

I'm sure I'll get alot of sign tapping comments to say about breakups, but it's easier said than just done. They feel like more than a partner to me, like family.

What would you do in my situation?

Is it worth me continuing to work on myself and maybe seek more therapy?
