So, @Giraffesandbottoms your family was packed full of abuse when you were growing up. your last comment is the key to the door.
They drink to excess and you do not.
They are damaged by the abuse & use alcohol extensively to manage their internal shit. You do not.
You see through them with clear sober eyes, & this makes for a great discomfort & unease for them. It feels easier for them to hurt & blame you than it is for them to acknowledge their own hurt & shortcomings.
‘Hurt you? Disrespect you? Nah, not really. You’re still here aren’t you? Besides, being in a family hurts, right? Have a drink, be one of us. Get over it!’
The ‘glitch’ for you is that you have a form of expectation that they are reasonable, calm & respectful…& oh, consistent - but these qualities are lesser known in abusive dysfunctional families, & each of their problematic drinking patterns are an expression of their significant inner disorders.
I see you as a bystander, a witness to their crazy, yet you still have strings of attachment that tether you to the circus where the same slapstick show plays on a loop. Yet you can see beyond this. The ties that bind you are pulled by them so that you do not get away & they need that audience. You are not going to get what you need from them.
You might find Al-Anon family groups helpful. You are the sober, clear sighted honest one in the family game of abuse, dishonesty & avoidance. Al Anon family groups
You do not need them to acknowledge their lying, it is enough that you know & go by your own knowledge & lights. Call it out if you feel compelled but don’t expect anything honest or useful back from them.
‘Hey C, don’t bother covering up. I know that GF was at Mum’s lunch, she was seen there bold as brass. I am sorry for you that you choose to lie.’
‘Hey C, what a batshit crazy bunch of fuckers this family are…’
C: ‘eh?’
‘If they weren’t so awful, they’d be funny’
It’s not you, it’s them.
You can make some change for yourself by looking beyond them for insight & acceptance.
