This is not inevitable. I had 2 bad marriages. I’m so glad I didn’t give up. I know people who met “the one” at around age 50, 60, and 70 after nightmare marriages. We are blissfully happy with our partners. If I had applied your logic, I would be alone today. And being alone is fine if that’s your essential nature. It’s not if you are a relationship person. Think about who you are before you decide.
