Each person feels in unique ways, has unique values, beliefs, personalities, fears, morals, hopes, expectations, resiliency, weaknesses, and strengths, thus what could work and feel comfortable for one person, could be overwhelming or useless for another.
That's why I said to carefully assess your core needs and expectations set your priorities and based on what you are willing to afford, make a decision.
Based on your story it seems to me that this may not be the best time to confront him because of your academics and finances. Then I'd suggest not to push yourself even more now, focus on taking good care of your health and responsibilities, and once you graduate and can afford to change things, work on these serious issues, without denying or sugarcoating anything. And unless you believe, feel and want to afford telling yourself a person who loves you can also at the same time be dishonest, manipulative and unloyal, work on improving your views and ways to approach relationships, to ensure your health, happiness, and well-being.
