I am in a similar situation and asking myself the same questions. In fact, I have been trying to think where or how I could get some answers/directions.
About me, 74 in relatively good health and shape: Also younger wife who for many years expressed an interest in traveling. Our marriage has been more one sided--me loving her a lot more and me trying to make it work. So for the last two months or so, I have been talking about getting a travel trailer and doing some traveling. We visited some dealers and went to the Tampa RV Show (we live in the area) last month, January, to look at trailers.
I found one that I like, Rockwood 2205S (23'10" length), and put a deposit on it. I am not a truck person, so, I needed to buy a truck to tow it with. After much looking, I bought a 2020 Ram 1500 Classic Crew Cab on Jan 29th. On February 10th (just 12 days after I bought the truck), my wife tells me she wants a divorce.
So what do I do now? Do I go ahead and buy the trailer (approximately $27,000), sell the new truck, which has less than 200 miles, for a loss, or what? Traveling and seeing places that I haven't seen and doing new things sound interesting, BUT I do NOT, repeat, do NOT like doing things on my own. Of course, I do things on my own, but they are not nearly as enjoyable as when I am with someone. For me, it doesn't matter what I am doing--watching TV, shopping, or whatever, it is nicer doing it with someone.
That said, if I did complete buying the trailer and went traveling, I am afraid that I would be extremely lonely and not be able to enjoy it. I might as well stay home and be lonely.
What I haven't mentioned is that I am an introvert. Meaning that I am not outgoing, and never have been. Meeting people is very hard for me.
Trying to figure out what to do and the best, is very difficult. Good luck to both of us.
