Are you afraid that you can't accomplish your assignments without him? Are you scared that you wouldn't be able to find a better partner for school projects? Are you afraid of telling him what bothers you about him because he might not like you anymore?
This is probably true. But how can I surpass those fears? The problem is that this relation is good in certain areas and bad in others, but I think in the end that the good about this relationship surpass the bad, so I think I shouldn't cut the relationship, but I still want the bad points to change.
