Why doesn’t anyone listen to the youngest

It’s like every time I fucking talk, no words exit my mouth. No one listens to me and it’s fucking annoying. Just because I’m younger than you doesn’t mean I don’t know what I’m talking about. I have very open opinions about people and I can usually tell if people are nice or not. It’s just a gut feeling but still. BUT NO ONE LISTENS TO ME EVER “he’s manipulating and controlling it needs to stop. I don’t want you to get your heart broken”

NOT EVEN ONE MONTH LATER

I find out, he has his fingerprint in her phone, they haven’t even been together a month

He told her to stop talking to so many people

He told her he was “hurt” for her talking to someone BEFORE they even fucking met.

And HE BROKE UP WITH HER

Guess what, the NEXT FUCKING DAY they get back together

I know this dude is just going to fuck her up and I’ve made my thoughts on him very clear. But does anyone listen to me? No

Because I’m young and “don’t know anything” or “don’t know what I’m talking about”

I’m probably handling this in an immature way but I’m upset.

I’m always a mature person so I don’t know why people always look down on me and tell me I’m wrong on things where I have fact-checked them or absolutely know but oh well
