Is this a valid reason to end a relationship?

I need advice.

I'm in a relationship that i feel trapped in. Even though i could leave whenever i want. 02/17/2026. Not even two weeks. I started dating a girl named Natalie. I have known Natalie since 2023. 2023 had to be one of the worst times of my life. I would not like to get too deep into it. But i was in a bad financial situation until 2024. In 2024 Natalie had asked me out. And i was very confused. My feelings about her were mixed. I thought she was sweet. But i lied, and said i should be focusing on schoolwork. And fixing my situation. Fast forward to now. I feel uncomfortable talking to her on discord. She gets jealous easily, and has made it very clear she wants to be intimate with me even though we are both young. And she has come out to me and admitted she was smoking. Smoking is a major turn off for me. And her friends have also made it very clear they do not like me. My sleep schedule is always all over the place. And her friend called me "gay" "red flag" and "bad boyfriend." All of these are making me uncomfortable and it sucks i can't say anything back to them. Nor does she defend me. So long story short. She's jealous. Does activities i do not like, her friend's do not approve. And she is possessive over me. Are these valid reasons to break up with her even though the relationship hasn't even been two weeks long? Also 18M 19F
