Maybe, but your woman needs a stranger to tell her what's wrong, and what she needs to do to make it right. She won't listen to you, but she might listen to a counselor. This stranger will likely have tips, tricks, suggestions for both of you on how to deal with the problem.
BTW, your response is typical of people who turn down help they desperately need, because they are too proud to admit they need it.
