I had the same sort of thing happen. First it was when are you getting married? I finally told a couple of people who kept asking that question I was going to hire hookers instead, it was cheaper. Those people got mad but also took the hint and shut up. Then when I finally did get married (I was 41, my wife 43) the inevitable questions about kids came up. My wife was unable to have kids which worked fine because I wanted no part of being a parent. Nor did my wife. So then we were asked why didn't we adopt? We got tired of that too so started saying it was nobody's business but ours. And, after my wife passed away 15 months after we married, I started to get the inevitable when are you getting married again questions. It's been 12 1/2 years since she died and I haven't been so much as on one date since. That fact has pretty much answered that question: I'm not!
Please accept my sympathy over the loss of your wife after such a short time. I hope it left you with good memories.
I know quite a few people who are aware that they are happier with the companionship of good friends, when they want it, than they would be with a full-time spouse in the home. If that's the case, it's good to know ones-self.
