I will correct only the third sentence.

A woman commented that he didn’t seem like a guy who couldn’t find a girlfriend.

However, another man jumped in and said, “You hasn’t bought a house yet. No woman will want to be with you.”

The Misery Man

There is a man who hasn’t been married by the age of 30. The incident becomes the topic of his office. A woman commented that he didn’t seem like a guy who couldn’t find a girlfriend, but another man jumped in and said, “he is pretty much like those guys, because he hasn’t bought a house yet, ‘No house, No woman will want to be with you’”. The office became silent immediately, the unmarried man became trapped in his thoughts and his eyes darkened.
