1. How long had you been dating when you became engaged?
2. How did he/you propose?
3. a) Did you pick out rings together, or did he pick for you? b) How did that work out?
4. Will you show me your ring?
If you have not been engaged:
1. How do you wish someone would propose to you/how do you imagine you would propose to someone?
2. Will you show me your dream engagement ring?
3. Imagine you had talked about marriage ad nauseum with your SO, and you both knew you were going to get married. How do you get them to quit stalling and propose already?
