Try asking him - perhaps as a light joke. "Hey, should we pick a date?" Or ask his opinion on types of weddings - would he like a big formal one, or an intimate, informal one with friends, or maybe one on a cruise ship?

Hi, I don't think he's stringing you along. Maybe he has reasons for not bringing you to altar yet, maybe he's making sure that you'd get along very well in a long time relationship. As long as you're in good terms, there's no need to panic.

No, I don't think he is stringing you along but then for me marriage is not a big deal. The quality of my relationship is the most important thing for me. It sounds like you have a beautiful relationship and isn't it enough to know he loves you enough to want to marry you? Sometimes the pressure to go further in a relationship will kill an otherwise good one. I say, just enjoy each other and your time together. If you live together happily as you are now for another 10 years then you are better off than many married couples that I know.
