Douglas feels indifferent about his mother's death because he never got to know her
Explanation:
why? Its because we don't exactly know what happened and why he has the emotions he would have felt if a stranger died even at his mum's death. Its possible that he didn't really connect with her or know her ,which we are not sure of,so its safe to go with the third option
Probably you should just do something nice for her and see if she does something back to you. If she doesn't then she isn't interested in you. But if she does something nice, she is definitely into you!
