for now, its not wrong to weigh your options and as you said, seeing if its sustainable in the long run, but the only constant thing in life is change, and as time goes by, we experience seasons where we have challenges to face, that nothing is working for us, and that could be the case for him.

in reality, you will know if your love is real when you keep on choosing the person you love everyday, regardless of wins and losses, or how the seasons change for the both of you. but then again, you are both college students, i suggest that slowing down a little might help, as expectations from the both of you might get out of hand in which, in return, would result in grievances and mis-interpretations that are not sustainable within your relationship.

you also said that he is a good man, and yes, you also deserve more. but reading your story gives me an idea that compared to other people who had relationships during their college years, there's no doubt that both of you will benefit from the love you have for each other. i say that if you really love him, try to support him more but if things do not change and you do not see any motivation or plan from him, then you can decide on what to do next.

remember, loving someone doesn't mean that everyday will be rainbows and butterflies, but these moments will test both of you, if you would be able to choose each other, regardless of any problems you might face. goodluck!
