Some backstory: 

I'm 23, have a full-time job, and recently moved back to my hometown so I am currently living with my parents.

My cousin (3 years older) is getting married this summer.

I have been invited to the wedding on my parents' invitation with no plus 1.

Am I the asshole if I dont buy her a wedding present?


Bonus:

She refused to invite grandparents and select aunts/uncles to her wedding due to concerns about seats, but she made sure to invite her "close" friends (roughly 20-30), some of whom she's known less than a year.
