First of all, you should tell your father-in-law, not that he will give you his daughter's hand and go with you. . .
To your father-in-law, you can say: Dad, thank you for your trust in me. You gave me the baby you raised for XX years. Starting today, you will have another son. I will treat XX well and honor you and mom all my life!
It's not time to talk to your wife. You should take your wife's hand across the red carpet, walk onto the stage and say to her: XX, we have been through so much, and this result is my dream, and I am very happy, because I am an old hand. Marry me! ! Kneel on one knee ~ wear a ring ~
