How can I leave my husband?

I am so ready to leave this marriage. Neither of us our happy and it’s toxic. However, I am COMPLETELY dependent on him. He works, I stay home with our daughter and I’m in college full time. I have no idea how I would afford things if we separated. I literally have no time to work. I feel so stuck and don’t know what to do. Help please 😞

*** for those questioning, I’m not being abused, thankfully. Just very unhappy in a loveless marriage. So motivated to get my degree ASAP so I can leave though 👩🏻‍🎓
