It's saying she's not worth a second chance To You because you're not going to marry her, regardless of the reason. How egotistical does a guy have to be to say about a girl that she's so pitiful that he needs to humor her with a second date just so she doesn't feel bad? If that's not objectifying women, Idk what is. You're basically saying "I be'eztem don't think you're worthy of getting married to anyone but I don't want you to think that so I'll pity you with a second date." What if you were saying no because you didn't like her personality, would it be ok then to not go out again? Because you didn't like how she looked, nobody else will? Do you see how this starts to spiral out of control?
I'm sorry, but you're completely missing the boat. You need to look at this from her perspective to understand.
Yes, you are telling her that to you she is not worth a second chance. This can be hurtful to anyone, even the prettiest girl in the world, unless it's a mutual agreement that it's totally not a match. This is not about a guys ego, it's about being sensitive to a girls feelings.
If a woman said no after one date would you be offended?
Why are we bringing guys feelings into the picture?
I know someone who got a no after 1 date and was hurt by it, they said what did I do that was so bad to not be worth a second shot?
