There is no reason for such a thing as feelings. If you feel comfortable, you can stay together, but if you feel uncomfortable, you may separate. I loved it yesterday, but I may not love it today. And feelings can't fool people. Past experience can't explain anything, but when problems arise, even when we choose to break up, it must be the same choice for both sides. Enjoy your time together, sit down and talk about it, deal with the problems you face together, and try not to let the breakup happen. After all, being together for so many years shows that you all enjoy your time together, which may be the best for each other. It's normal to have new feelings or try new things, but today's distraction or infatuation is more likely to be the result of ignorance. But don't hurt each other. Breaking up is no big deal. Nothing in the world is fixed, but even if we break up, it is best to thank each other for their companionship for so many years and sincerely bless each other, so as to live up to your years of getting along.
