Is it bad that I don't care if the relationship ends?

Like we got into an argument and he made me feel pretty shitty. He came off rude and condescending about things I went through with people and just other stuff. I told him I'm done and I need a break because it felt like I was talking to a brick wall and that he didn't care all he said was "good luck, I'll see you when I see you I guess". Lately he's been nonchalant about affection. Others can see in pictures we take that he doesn't look happy. I've done so much for him and it just feels like I'm not enough. He claims I am enough but his actions are different. Not much sex anymore, he's on his phone more than he gives me attention. He just acts like he doesn't care and that his love is conditional. He has childish temper tantrums got anger issues. His communication skills are shit. I just feel so done, I'm numb to if he decides to come back I wouldn't care or want him to.
