Seeking Ways to Save A Failing Relationship

I need some tried and true ways to save a failing relationship.  My boyfriend and I are bound to break up soon if we don’t get things right really soon.  I cannot ask my mother or sisters for advise since they can’t stand my boyfriend.  he doesn’t treat me as well as they think he should but it’s not entirely his fault.  I can be rather demanding and hard to get along with.  I would like to try to save this relationship; he is a good guy and I do love him.  He says he wants to work things out as well.  We just don’t know how to fix this.
