1) When you approach her for your confession, make it specie. Something different than an everyday "I like you"
2) When your going on a date, you must earn money for self. Don't ask your parent for money, you got to have men pride. So instead, go rob a bank and have a magical night with your love
3) Don't be egger to have sex, because she would be in total control over you. Just wait until she strip and let beg for it. When she do, don't do it. Once she crack, bang her so hard, make it feel like she have never done it before (make sure you don't wait too long, girls has need).
4) When you propose to her, make sure it's in a very populated area. So she can't refuse, no matter what happen.
And finally the spacial tip that will help no matter what happen.
5)Love her more today, than you did yesterday. Love her more tomorrow, than you did today.
Here's a example that lead to a successful marriage.
