Have I made any mistakes?

Maria was thirty-seven and not bad-looking, but she was getting desperate to find a husband. Her main problem was that all the men she had a relationship with couldn't satisfy her criteria. They were either ugly, boring or didn't have a high-paid job. Someone told her that the man she was looking for didn't exist, but she was so stubborn in her pursuit of that ideal husband that nothing could discourage her from believing her marriage was just around the corner.
