Although my relationship with my GF is pretty solid(We've been together 3 years), she is cooperative and open to many problems and projects we share. But sometimes, when I want her to understand the give and take in relationships, she will dismiss my requests with "I don't like it". It has nothing to do with her exposing herself to pain, danger, health or other things she has every reason to reject. It's a shortsightedness,IMHO, of understanding that pleasing your partner strengthens the relationship and turning your partner down weakens it. I try to emphasize that she has proven to be open about a lot of things(which I love!), but irrational about others. How to handle this and make it a plus instead of a minus?
