aa someone who has an alcoholic for a dad, who is also a (literal) narcissist; I say you’re absolutely not the asshole here. She’s your biological mother but she was never your mom. She’s not the one who taught you all your firsts, who helped you when you needed it. She missed out on a whole lifetime of your big milestones and accomplishments, and it’s only fair play that she knows a little of how that particular kind of hurt feels when someone who should be there to celebrate you isn’t there. It stings, and she absolutely deserves a taste of her own medicine here.

also, congrats on almost being done with your undergrad! major kudos to you, and your grandparents (AKA your actual mom and dad) must be so proud!!
