Dreams are subconscious thoughts and behaviors. Maybe you don't feel your dependence or love for your boyfriend in your life, but what this dream tells you subconsciously is that you are very afraid of your boyfriend's betrayal, both mentally and physically. Relax, feel with your heart whether he is a good man or not, just trust him.
Or he did something to hurt you before. Although you forgave him, you can't accept his disloyalty to you psychologically.
I am still the same sentence. Feel his love for you with your heart and trust him.
