Is my 27 year old sister jelous and over reacting that I am dating a guy that went to high school with her?

I am 18 years old I am so mature for my age. My 27 year old sister she acts so inmature she is so jelous of me. I am dating this hot 28 year old guy he asked me to be his girlfriend. He even says that I am way more sexy and beautiful then my sister. He even said that my sister is hitting the expire date lol. Oh my god he is so cute and sexy. The sex is great I am trying to get pregnant with him. I even told me he wants to marry me. My sister she is jelous of me because I am more younger. My sister and my boyfriend went to high school together. He was the quarterback in the popular quarterback 🏈 football team at the time. My boyfr8end works at mcdonalds. My sister got so angry when she found out she says that he was a player back in high school that he got a lot girls pregnant back in high school and that he was a prankster. Not my fault he never put eyes on my sister. My sister and I got into an aurguement she says that he is way to old for me that I am an easy target for him. My sister she is so old and jelous because I am younger and win chances with the hot guy she could never date. My sister also went of on even saying that my boyfriend has serious issues only because he isn't dating girls his age that why is he chasing after 18 year olds. She even called my guy a looser for working at Mcdonalds according to my sister my boyfriends should have move up to the next level after all this years by now. Worst thing she told my parents and my parents scream at me but what can I expect my parents are old 50 year olds. Thanks to my sister it got worst she told my parents lies about my man how he was a jerk at high school. Well my sister was a geek. How can I make my sister face it that he wants me and not her?
