Has your partner ever told you “I hate you” during an argument

I understand that when we are angry we say really mean stuff but I have never told my bf I hate them. As much as I’m angry I watch my words. The worst I’ve said was “I need someone who values me”

This has been the 3rd tjme my bf tells me “I hate you, I really do” he has said in Spanish which sound more powerful.

Weeks before he has told me he loves me a lot and I’m the love of his life. How can people say this to your significant other??

I feel fucked in my head. I screamed at him and said “if you hate me why are you with me?”
