Thanks, yeah I am very confused and idk what I want or what is right anymore. I feel like he has good intentions and he is trying to help us but the way this is making me feel is just horrible and I just don't want to have to feel like this and that is what is making me doubt everything. Like i am worried even if we resolve this I'll be worried if we have another major problem he'll deal with it in the same way and I'll feel just as bad. I feel a little emarrassed talking to people about this tbh and also he wants me to keep financial issues between us but maybe it has got to the point where I have to as I feel so awful. I don't think he is abusing me though he is just trying to help but in completely the wrong way and he seems to think I am clueless at this which again upsets me
As an adult, you have the right to make your own decisions, even if they're bad ones. As I mentioned in my first post, if your DH thinks you're always making bad decisions he has the right to choose to leave you. You also have the right to choose to leave him, for whatever reason. The reason doesn't have to be "reasonable", so it's not necessarily a question of working out if you're being unreasonable. As an adult, you have a right to be unreasonable (just don't expect others to like it!). So if you want to leave DH over his behaviour, that's fine and you don't have to justify it.
There's a certain type of abuser out there where everything is "for your own good" so it's quite hard to spot the controlling behaviour because its portrayed as "concern" for you and necessary for your wellbeing.
"Confused about right and wrong" is how abuse makes you feel, so I see your confusion as a red flag.
The fact you "feel horrible" about the situation but can't put your finger on why is also a red flag. You don't feel this way for no reason. Your gut instinct is trying to tell you something isn't right, but "not right" is normal for you so you can't see what's "not right". A person might feel horrible if they've done wrong and feeling guilty for their behaviour, but I don't think it's that because you mentioned the future and a fear of him behaving this way again. You called it "worry" but I think "fear" is an equally accurate word. I think if it was guilt about your own behaviour you wouldn't have this fear, because your own behaviour is within your control so this situation wouldn't occur in the future. So it sounds like you're afraid of him/his behaviour in dealing with problems in general.
With "keeping financial issues between you" there's a difference between telling your private business to all and sundry, eg your friends and acquaintances, and telling people anonymously on an internet forum. We don't know who you are, so it doesn't really count as telling people. You can't get advice without telling people the problem and details. Imagine going to the doctor about an STI but not telling them the problem was with your genitals or happened after sex, because those things are private. Sometimes it's necessary to tell certain things to certain people. It's also true that abusers don't want anyone to know about their abuse, so they'd much prefer you don't tell anyone! They have a habit of inventing reasons excuses for why you shouldn't tell anyone ever about what's going on.
Thinking you are "clueless" is putting you down and to repeatedly state it would knock your confidence, even if it's true. Imagine if someone is fat. That can be said as a statement of fact in a non-negative helpful way eg have I put on weight? Yes you are looking a little fat, shall we go for more walks at the weekend? Or it can be an abusive term eg FFS you fat cow why don't you eat less?! The latter is not ok. Of course, it might also be that the person isn't fat anyway, even if they're getting abuse for it. If you are clueless, you can educate yourself or find ways round the things you struggle with, but it should never be used as a way to put you down even if it's true.
I still don't agree with your attitude towards paying your parents and in-laws back, about it not mattering because they're not chasing for repayment, but that's a totally separate issue to whether or not you're being financially abused (and it looks like you might be).
