Most Helpful Girl
Here is something I read once, and it seems to make sense for this question. Just because someone doesn't love you the way you want them to doesn't mean they don't love you with everything they have. Sometimes people just don't put the effort in you expect they should. Some people... like me will try 10 ways to Sunday to try and make things work without walking away, and others just can't seem to muster the effort to try to make things work better. So it really depends on the person.
