Frumeyid-
I agree with your post 100%
Sac-
I’m sorry if I jumped to conclusions about your experience. Usually when someone has such strong feelings on a particular subject, it is because they went through it themselves.
You sound like a very sensitive friend, and you take your friendships very seriously. You say that you should ask your friend permission to date the guy. What if she says no? Would you seriously not date someone because your friend does not approve? That is taking friendship a little too far. Some people date regardless of their own parents opinions, and you say you would not date someone because of your friend? That is a bit intense.
At this day in age, when dates are so hard to come by for the average girl, I highly doubt that anyone would pass up a date in respect of their friends feelings (which are probably incorrect to begin with)
