How about marrying far away? What should I do? Very painful.

You lack the confidence to strive for happiness, especially him. A gentleman still has the courage to support his wife even if he has a bad time. He said that he couldn't give you happiness, which showed that he was weak and didn't have the courage to face the ups and downs in life. Don't let this man go! But then again, if you love him, you should encourage him to face the difficulties of life bravely and let him have the confidence to fight for each other's happiness instead of being sad and complaining blindly. It doesn't make any sense, it will only lead you to be more cowardly in the face of feelings in the future, and the final outcome is likely to be to find an uncle who can only support you.
