Ask your girlfriend how she feels about you and your relationship. Before you can tell her you want to marry her, you have to make sure that she feels the same way you do. Her answer to this question will tell you what you need to know about your next move.

Shop for engagement rings. Once you are certain that she loves you too, you should begin shopping for engagement rings. Recruit her best friend or mother to make sure you get a ring she likes.

Plan a romantic evening with your girlfriend. The entire evening should be filled with romance such as a romantic dinner at a nice restaurant and something you both enjoy doing together. Once the mood is set, the moment will be right to tell your girlfriend that you want to marry her.

Tell your girlfriend how great she is. As you begin to propose, you should start by telling your girlfriend how wonderful you think she is and how you can imagine spending eternity with her. This will simply be a build up to the actual proposal.

Present her with the ring and pop the question. You can decide to be cute and place the ring in a champagne glass, but it leaves too many unknown factors. Present the ring in its box and tell your girlfriend how happy she'd make you if she accepted your offer of marriage.
