Make a meal, then call your potential mate over. Sit down and eat with them. When you are done, let him or her use the bathroom. While they are doing that, watch TV then have him or her join you. When they get up, propose.

Eat dinner with someone. They will use the bathroom. While they are in there, watch television. When they leave, highlight them and the "Propose" option should appear. You can also have a baby with this person by getting the Love Tub. Mimi or Dudley are the best choices, because they will pay all the bills.

When you get the "Propose" social, serve a meal. Invite your lover over and have them get a plate of food. They will go to the restroom then go swimming. When they get out, propose. Note: You must have a pool before they get to your house.
