Would you/could you be married for 35 years? (btw, to the same person)   stance: yes, if it is to the right soul mate & love of your life:
Yes, it isn't that tough, my grandma got married for about 50 and that only ended because she died. I've been married for 7, Johnny Cash was married to June Carter for more than 40, George Takei has been with the same guy for almost 30, people do it all the time. This world is filled with hardship, trouble, pain, financial crises, toil, so it becomes that much more important to be with someone who is special and who loves you even in your darkest hours. I might seem like a cynic and a skeptic but there is nothing I believe in more than I believe in love, the love of my parents, the love of my siblings, the love of my wife, the love of my kids, and the love that I feel for all of them in return.
