Advice?

I need some advice. Currently my boyfriend and I live together. He’s so sweet and kind and I love him. This is the healthiest relationship I have ever been in. But I’ve come to realize that he’s not the one. I’ve thought long and hard about this and I know I need to end things. The issue is that our lease isn’t up until August and to break it is $2,000. I can’t afford it as well as get a new apartment at the same time. I would move back home except I go to school in the town I live in and my parents live an hour and a half away and my degree offers no classes online. It feels wrong to wait until August to end things but I don’t want to screw him over for rent. And I feel like I should give him time to find a new roommate or living situation. I don’t know what to do honestly. I’ve considered telling him that I want to move out because of school and that I can’t focus because we’re living together but that also feels wrong. I don’t know what to do. How do people break up when they live together?
