Band w/ friends pt 2 ig

I didnt know if i was gonna write again about this (see other post for context) but stuff is getting deeper 

-----skip this part if u don't want added context----

For some context i didn't add to the last post- Were a newish band (it's been about 6 months since inception and about 5 since the lead guitarist in question joined) but we've made it clear that we want to actually make real music and not just play in our singers basement for fun (no hate to my fellow basement bands) 

If i dont give sm sort of names to the people in question these posts are gonna get confusing fast so 

Me - val/valentine, he/him : Singer/rhythm guitar - star, all pronouns but for story we will stick to he/him: Lead guitar (the problem(?) person) we'll say lemon (makes sense to those who know them) they/them: drummer- Cat he/him

these names are totally made up btw

----ACTUAL UPDATE----

Lead guitar/lemon and i talked today because we had a misunderstanding which started yesterday (sparking my post) which has now blown out of proportions into them unloading everything ive ever done wrong at once. following our conversation yesterday (it sounds like im skipping a section but they actually just left me on read and now its today) about me "saying something judgmental" about them (according to someone else(whom does NOT know me) i asked a pretty genuine question: Do they think i would actually say something like that about them? 

and Lemon said that they didnt know if i had a problem with them because we hadn't been talking/hanging out much (recall that they had been cancelling on us a lot recently with little to no explanation) 

i say that it's true we havent but do they really think i would judge them behind their back just because weve been busy and not spending as much time together (they say ig) so i point out that even if i WAS upset about it i wouldnt go gossiping behind their back and that i felt like they were upset with me even though i didnt do anything (at least not intentionally) and reinstated that i didnt mean anything it was just a misunderstanding

they rlly tell me that they ARE upset because ive been saying underhanded things lately? 

I honestly ask what ive done because if i did do anything that hurt their feelings it wasn't on purpose and they never said anything until now

they claim they didnt want to start something (and i point out that something objectively worse is being started now because they never mentioned being upset by anything i did and just sat on it before now)

Lemon says they didn't want to make a big deal out of it and I tell them that it isnt a big deal to tell someone "i didn't like that pls dont say that" when someone does smth and if were friends they can just say it

They mentioned smth specific i said earlier that week (which i apologized for) and that i apparently would say the same thing in school?? (im one of those people who abjectly remember like NONE of school) but i apologize again and say AGAIN that i have no memory of saying that/ school in general. 

They then go on to complain about (personal issues) directed at me on things they never thought to like ... idk... TELL ME ABOUT WHEN IT HAPPENED and when i have the (audacity) to ask why they never said anything they said it was because they thought "the issue would resolve on its own" ( i didnt know there was an issue/ i didn't think it was an issue )

Im not under any circumstance saying im a saint or anything (not even close) but can I just end this update by saying 1 thing

HOW AM I SUPPOSED TO FIX SOMETHING IF I DIDNT KNOW I WAS DOING ANYTHING WRONG??
