The first prayer is a Novena to Saint Joseph, the spouse of Mary. This novena (say it 9 days in a row) isn't especially for future spouses, but you can customize the request
"Oh Saint Joseph whose protection is so great, so strong, so prompt before the Throne of God, I place in you all my interests and desires.
Oh Saint Joseph, do assist me by your powerful intercession and obtain for me from your Divine Son all spiritual blessings through Jesus Christ, Our Lord, so having engaged here below your heavenly power I may offer my thanksgiving and homage to the most loving of fathers.
Oh Saint Joseph, I never weary contemplating you and Jesus asleep in your arms. I dare not approach while he reposes near your heart. Press him in my name and kiss his fine head and ask him to return the favor when I draw my dying breath.
Oh Saint Joseph, Patron of departing souls, pray for us.
And this one:
Remember, keep praying. If it is meant to happen, it will.
