Do you think it's okay if I ask my friend's crush out on a date?
Are you asking out your friend's crush as a trick or a joke?
No, I'm doing it because I like him.
Even if you personally like the guy, it is inappropriate to try to pursue someone that a friend is already interested in. if you go out with your friend's crush, your friend will emotionally suffer and you will jeopardize your friendship. Rather than put your friend into such an uncomfortable situation, you should try to pursue someone else who is not connected to your friend and is single and available.
I can't help my feelings. I don't care about my friend. I will just save all my feelings and emotions to myself.
It's selfish to only think of yourself and not also your friend. If you do it, be prepared to lose your friendship. Be sure this person is worth it to you.
