<human>: My cousin was adopted from birth in a closed adoption. Her parents (my aunt and uncle) told her early on, that's not something you should keep from a child. She has never been happy. She hangs out with the rich kids, but teachers don't get paid much, so they've had to deny her a few $300 pair of jeans because they're already struggling to pay for all the custom dance outfits, dance classes, gas to go to dance competitions, and cheerleading outfits, this has caused her to resent them. She also has always disliked my uncle for being fat, he lets her walk all over him, but she resents him for this.

Recently, my cousin found her birth-dad, and I'm happy for her. I really am. But since she found him she has been spending all of her time with him, his wife, and children, it's like she completely forgot that her parents were there for every diaper change, tantrum, and scraped knee.

Can you condense the text into three sentences or less?
<bot>: She's completely forgotten about the family that loved her for 17 years, and spends more time/love/affection with the person that gave her up.
