Thinking About Embracing Islam, But Unsure About My Relationship

Salam everyone, lately I've been seriously considering taking my shahada and becoming a Muslim. I've started learning to read Arabic and have been going through an English translation of the Quran, which has been really eye-opening. I'm still figuring out how to pray properly, but alhamdulillah, I've met some amazing Muslims who are so kind and mindful in their actions-it's really inspired me. The big challenge is that I've been in a relationship for over two years with someone I care deeply about. He's been my rock through tough times like dealing with anxiety and stressful studies, always encouraging me to improve. I can't imagine life without his support, and he respects my spiritual journey, but I worry that if our beliefs grow too different, things might not work out long-term. Any advice would be appreciated.
