Will They Make it to The Altar?

He's been waiting on her for 9 years. Every time he proposes she ask for more time. She is unemployed, he is retired military with couple rental properties at 100% occupancy plus a supervisory job. Everything she needs he gives her. The friendship is great, conversation is hours long. Now am I crazy to assume that in this economy he is a perfect candidate for a husband. We are always told that you should be friends first, so if they can tolerate being in the same space and stayed friends for 9 years, why not take it to the next level. He's divorced so he knows what he's looking for, her on the other has been single for the 11 years and love living by herself. In that 9 years he has not dated anyone else but how long is too long to wait around. Maybe she's comfortable in believing he won't leave but a good man like that is always in high demand. In my opinion, he should make himself scarce and let her realize his value. I'm ready to snatch him up myself.  Is it premature to assume that she will only say yes after he's found someone else?
