Is this incorrect of me?

I (19M) and my girlfriend (19F) have been together for nearly a year, and our anniversary is coming up soon. However, I'm starting to feel like I don't want to continue the relationship. Her mood seems to influence everything around us. When she's unhappy, it feels like no one can be. **She spends all her time on her phone,** often doing things that seem trivial, like checking her friends' Snapchat locations or scrolling through Instagram. She insists on having my Life360 location shared all the time, and she frequently tries to instigate arguments because I don't post pictures of her on Instagram. Additionally, I've caught her going through my phone without permission on several occasions. She also doesn't have a job, and when I'm not with her, she tends to just stay in bed all day. Even when I'm at her place, we mainly just lie around doing nothing. Is it wrong for me to want more from this relationship? I want a girlfriend who’s excited to go out and do things with me, who listens to what I say, and isn’t preoccupied with social media. Things are relatively okay between us at the moment, so I feel guilty about the idea of ending things. Should I break up with her? Any advice would be greatly appreciated.
