Here, a "commitment" is something you are dedicated to and have a responsibility for. Ex: I have too many commitments. There's college, tennis club, weekly social group, looking after the dogs, and I still need to take care of myself. Maybe I should stop playing tennis a couple of nights a week. Ex: She has a commitment that night, so she won't be able to join us for dinner. Ex: I committed to helping with the project, but I don't think I can.
