Should you instantly comfort them because theyre hurt, regardless of whether theyre blaming you, and whether or not you think theyre right or wrong?

Or if you feel that they're blaming you for something unfairly should you express that you think that its not your fault, and why it isnt. Because it hurts you that your partner is blaming you.

For example, lets say girl cries because girl says "lets go to dinner together on friday" and boy says "i think that would be great", but girl thinks boy is being sarcastic.

Should boy say "im so sorry i hurt you" or should boy say "oh, i didnt mean it sarcastically, i was being sincere."

What if the boy says option 2 type answers all the time, and the girl is like "i dont want an explanation, i dont want an apology. If you loved a girl would you ignore the fact that shes blaming you and just give her the sorry she wanted, because shes hurting, or would you say "i cant just apologize if i disagree with what you're saying, i have to explain my actions."

What if you explained it wasn't your fault but the girl still thought it was yours, would you get into a fight, knowing that shes hurt, or would you just take the blame.

My girlfriend says if a guy loves a girl he'll just console the girl because shes hurt and because he doesn't want her to hurt. I say its not fair for the guy to be blamed without being able to justify why its not his fault if he thinks it isnt.
