Is it reasonable to break up with him because he doesn't make effort to see me?

Yikes. What have his past relationships with other women been like? Has he been burned? Did he have a rough time? Has he been told in the past, "I'm sick of you? Before you break up with him talk to him about prior relationships. What about his job? Can he afford to do things that may cost? I bet if you ask, you may get to the real reason. Keep trying and good luck.
