My Bosses (husband And Wife) Planned On Firing Me And Forgot To Change Emails On A Couple Things..can They Come After Me?

So, over six months ago I was working as the manager of a relatively new coffee shop. I was originally offered the job by a friend of mine who was the manager at the time. He had created the coffee shop’s Instagram account, gave me the login information, and told me I was responsible for posting a couple of times a week and also told me i needed to change the email associated with the account to my email, so I did. I ended up working there for about a year and a half and I genuinely did my best. I knew nothing about social media, coffee, and definitely knew nothing about being a manager but i got really good at it. Or so i thought. I received basically zero support or guidance from the owners and the only real feedback I ever got was essentially “You need to do better because we’re still in the red.” That was it. No actual direction, no suggestions, no real help. After being there for a year and a half I called my mom and told her “I’m pretty sure they’re planning on firing me” because they randomly started asking me to give another employee all of the login information for stuff and had me train her on everything as well. And then BOOM..about two weeks later I got super sick was out for a couple days and when i returned to work i was met at the door, asked to hand over my key and was told i was no longer an employee. (That was all I was told btw..no reason) Well a week after getting fired I got another job and moved on with my life but then about a month later I randomly got an email from Instagram that had a login code for the coffee shop Instagram and I also got a text, from who I assume was the new manager, saying something along the lines of “Hey, I know this is weird, but can you send me the code haha.” Well I ignored it because..no. At that point, I had already been fired and removed from everything associated with the business. I assumed they had handled whatever accounts they needed to handle before terminating me because they asked me to hand over the log in info to everything before they fired me. In my opinion they should have crossed their T’s and dotted their I’s. ????‍♀️

Well about six months later, completely out of nowhere, the owner texted me asking me to send him Instagram login codes and I ignored that too. Then the next day I received ANOTHER text from the same girl and was told that I also needed to “transfer ownership” of their Square account but I genuinely have no idea what they are talking about cause I do not have access to their Square account, I am not using their Square account and I have nothing to do with it. Well my fiancé got pissed that after how horrible they treated me (i was coming home in tears at least 3 times a week, i was having panic attacks AT WORK, i started having stress headaches, my hair started falling out and i got a stomach ulcer...from stress) they had the nerve to ask me for help so he reached out and told them that I would not be communicating with anyone from the coffee shop and that I do not have anything to do with their Square account and he suggests they find a different way to figure out the problem cause I'm not doing anything to help them ever again. The owner was semi-polite at first but i guess once he realized I actually wasn’t going to help them, he suddenly accused me of stealing. Keep in mind there was never any mention of me stealing anything before I was fired. There was no mention of it when I was fired. There was no mention of it afterward. There was no mention of it when I specifically made sure I would still be receiving my final paycheck. Nothing. This accusation only came up after I refused to help them regain access to accounts they apparently failed to transfer when they fired me. They also HAVE access to the Instagram account..like they post on it every day. I was booted off of it not even 30 minutes after they fired me. Same with Square, I have no access to their account whatsoever and genuinely don't even know what they want me to “transfer" because I got kicked out of that as well. Anyways..i just want to make sure that I’m not doing anything illegal by refusing to get involved or help them with any of this. I haven't accessed, altered, deleted, taken, or interfered with anything. I simply don't want anything to do with a business that treated me like dog shit and then fired me AND is now accusing me of stealing.

(Edit because the bit about my last paycheck was confusing) I DID get paid my last paycheck (minus my tips but I chose to ignore that cause i barely made tips there due to the lack of customers) what I was saying was IF I stole from them or owed them money or whatever hes accusing me of, why didnt they mention it when I asked if they were still planning on paying me my last paycheck? The reason I say that is because when he made the accusation he said "when shes ready to pay us back" and when asked to clarify what he was referring to he said "she knows what she did"
