How can I (26F) best support my boyfriend (26M) as he pursues his MBA?

My boyfriend (26M) and I (26F) have been together for nearly two years. We met during a challenging time in my life when I was unemployed due to switching careers and facing financial difficulties. He was in a great financial position with a high-paying job. While he didn’t contribute to my bills or groceries early on (since our relationship was new and I didn’t ask), he frequently took me out to eat and surprised me with gifts, which helped improve my quality of life. When my lease ended, he generously allowed me to stay with him rent-free while I got back on my feet. However, after the first year of our relationship, he lost his job and struggled to find his direction. He made the decision to pursue an MBA at an Ivy League school, where he is currently studying. During this time, I secured a job in my desired field and earn a decent salary. I often visit him at school, staying for a month at a time since I work remotely. Now, I find myself in need of advice. He took a significant risk by committing to an MBA without savings and relying on student loans. He is now looking to me to help support him financially, which is creating tension in our relationship. My aspiration is to be a digital nomad and travel to immerse myself in different cultures, and I worry that contributing more to his goals means sacrificing my own. We aren’t married, which adds to my concerns about potentially funding his dreams without the security that marriage provides. Still, I don’t want to be an unsupportive partner while he faces these challenges. How can I help him without compromising my own dreams? I’m aiming to find a healthy balance that allows me to support him while staying true to my own aspirations.
