Is incompatibility a valid reason to end a relationship?

We are both 18 and have been together for nearly a year. Our love for each other runs deep, and I truly believe he is a good person who cares for me. However, we do have our disagreements, and sometimes it feels like we just don’t understand one another. There are moments when I need someone to empathize with me, which is a challenge for him. Additionally, he can come across as insensitive and lacking emotional intelligence. I also worry about feeling like I’m raising someone else’s child. During busy times, he tends to show less affection, which isn’t necessarily wrong, but I sometimes wonder if I’m asking too much for a consistent display of love. I want a lifelong partner, and while I love him, I'm unsure if this relationship is truly worth the struggle.
