Should I (24f) break up with my boyfriend (22M) over this?

Hi everyone, I (24F) have been dating my boyfriend (22M) for 6 months, and I’m struggling with whether this relationship has a future. I’d like some outside perspective because I don’t want to feel like I’m being unfair.

Here’s the situation:

1. He’s been in the military since he graduated high school at 18 and now wants to get out.
2. Hes doing a transition program that was supposed to help him land his “dream job” at a gun store, but it turned out to just be another minimum wage retail job.
3. He didn’t factor in how much rent and bills would eat up his pay, and now he’s struggling financially.
4. He’s considering college, but he doesn’t know what to go into. He mainly looks at salaries online without thinking about whether the field would actually be a good fit. For example, he’s talked about wanting to be a lawyer, but he was homeschooled, doesn’t have strong reading or writing skills, and he changes his mind constantly based on what he sees on social media. Recently he said maybe he wants to be an armored truck driver because he thought it seemed “cool.”
5. Overall, he doesn’t really know what he wants to do once he’s out, and his backup plan is just to move back in with his parents.

I have lightly suggested that he should stay in the military, maybe major in finance, or go to trade school, but he doesn’t really listen and thinks all of those options are boring. Meanwhile, I’m 24, a recent graduate myself, currently applying to jobs and juggling multiple side hustles in the meantime.

On top of all this, he calls me constantly. He wakes up at 5:30am and will call me until he leaves for work at 8am, and then will call again from 6pm until he goes to bed. It makes it really hard for me to complete things, and I’ve been falling behind. I’ve asked him if we could just call once a day, but that makes him sad — he’s even insinuated that he doesn’t eat when we don’t talk as much. He also needs constant reassurance that I like him.

I care about him, but I’m worried that he’s very immature and not grounded in reality. I want a partner I can grow with, and right now it feels like I’m dating someone who has no direction or plan, and is very dependent on me emotionally.

Is it reasonable to break up with someone over this kind of situation? Am I being too harsh, or is it valid to want more stability, independence, and ambition in a relationship?

TL;DR: My boyfriend (22M) is leaving the military, struggling with money, constantly changing career ideas without real direction, and is very emotionally dependent on me. I (24F) just graduated, am trying to establish my own career and side hustles, but his constant calls and need for reassurance are making me fall behind. I’m also getting freelance work from his friends, which complicates things. Should I break up with him because of his lack of stability and maturity?
