What should I say to propose to my girlfriend?

Don't copy and paste what you said when you propose. Although some words are romantic, they may not be suitable for everyone. You must say them according to your actual situation. You can talk about your past, present and future.

Past events: How did you meet, how did you fall in love, and what you experienced together.

Now: How long have you been together and how far have you been in contact with each other?

Future: Talk about your desired married life. How will you get along with your family, children and her? In short, you will be very happy and then show your determination to cherish and care for her.

Many male protagonists who proposed marriage were too excited to control their emotions and spoke the declaration intermittently on the spot. You made this proposal with your own heart. It doesn't matter if you don't sweet talk, as long as she can feel your sincerity!
