Why is it always have to be like this. 😭

Please pray for me :'( I have a narc boyfriend and it always makes me feel drained, exhausted, and hopeless. I can't leave him alone because I love him but affects my mental health :'( I always have anxiety and when we argue he always says he didn't do anything wrong. He always told me that I am sensitive and don't understand him which opposite of what I feel :'(
