Love and Narcissism

Love and Narcissism
What to do when you feel the other person is being really selfish and narcissistic in a relationship. Like when you talk, all they want to talk about is their day and what happened to them and how they are but they never actually care about how you are, how was your day or how you are feeling. Obviously if you love someone, you have to be there for them, listen and understand and help them out. But no they don't want your help also, all they want is to vent out or sort of be really descriptive. I mean how much can you listen, there's a limit. I don't want to take any action because I really love that person and I can do anything, even go to the extent of being absolutely numb. He also loves me and he does care about me but why does he use me so much. I feel so exhausted, you have to give me respect and care, you can't just take someone for granted like this. Is it just me being selfish, I don't know, I am trying, but if this continues I will really fall out of love with that person. I have starting to and just because I don't have anyone else right now, I have to continue to be with him but this can't last long. I will burst out one day I think. I feel like hurting him on purpose sometimes for what he does to me. Like cheating on him. He is really narcissistic.
I feel like going back to my ex. Who was way more toxic than him but just to hurt him. I know it's really bad for me to think like this but it's just feelings, I would never act upon it.
Just wanted to vent out
Thank you.
