Living together

So I’ve been dating my boyfriend for a little why now and I’m so in love with this boy I can’t even explain the feeling and so next year he is moving into his own apartment and I’m moving to because of school and he wants us to live together but I’m nervous too because it’s a really big commitment. And I feel like when you live together it’s serious and I don’t want something to happen and we end up breaking up and then it’s like someone ripping out my heart so I think that’s why so hesitate to say yes because I’m scared too
