My boyfriend lied to me means “the boyfriend lied about something to that person” or “the person thinks her boyfriend lied to her about something” I still hold it against him means “it’s his fault” and it’s I am still angry with him that means “the person is still angry with him” the feeling of hatred.
For an example. Pretend this is a scene or a movie.
The girl found out that her boyfriend cheated on her. When she went to see him, he played it cool like nothing happen. One day, the girl got frustrated and told it to his face then stormed out of the place. She went to see her friend and spoke about it and told her friend she doesn’t know what to do and she’s still angry with him.
