Its wonderful that you are sensitive to the voice of the holy spirit who is telling you to "just wait". Unfortunately in our humanness, we tend to be impatient and want things to happen quickly but God has his plans for us and only He is to one to unfold the plan. We just have to have peace while we are waiting, rest in him and let the holy spirit continue to work in our hearts so that he can mold our character to be like his.
I myself am in a situation of stress and unrest in my soul and many times, I want to bang my head against the wall (literally), but always the still soft voice of God saying, "wait, be still". So in all my frustration, when I want to give up so many times, God just gives me the strength to wake up each morning and to face another day with HIS peace, His strength (cause I'm weak), HIS mercy, HIS grace and HIS love. Through many years of suffering, I can look back and see that he has molded my character and I'm a much better person today according to his will and purpose.
May God bless you richly in your walk and may he restore your marriage and make the marriage even better than ever before.
