yes
yes.
More than likely. Because if he did not have feelings for her anymore then he would not be asking about her.
You have to be careful in this situation as this could cause problems in your friendship is she does not return your feelings. You should simply sit and talk with her concerning your feelings and take things from there.
If you have fallen for a good friend then the best thing to do would be to talk to them about your feelings. If you are really close, then even if it doesn't work out or they don't feel the same way, you should still be able to be friends. As I personally have fallen for a very good friend, I realize that it may be uncomfortable to talk to them about this. If they are really your friend then they will stick by you. Don't be nervous. Tell them how you feel!
then maybe you should be just friends
You should only ask the girl out if you like her. If you do not like her as more than a friend, asking her out could lead to hurting her feelings.
It would be uncomfortable, maybe you should talk to her first, is he worth losing a friend over ?
No reason to, you should move on to your next guy.
Be honest that you really enjoy being his friend, but you don't have any romantic feelings for him. You can't prevent his feelings from being hurt in this situation. This will possibly affect your friendship, at least for awhile. He may be too angry, hurt or uncomfortable to be close friends with you. Make it clear that you still want to be his friend, but give him space.
As soon as a friend hurts your feelings you should make it clear to them that they did so as soon as it is out of their mouth. Sometimes friends say things the wrong way and don't realize they have hurt their friend's feelings.
well you should ask your best friend for his/her approval.Because they may feel uncomfortable with you asking out their sister.So approve that first,Then just go up to her with the highest confidence and say id really enjoy it if we could start dating and see where it takes us on from there.
If you value your friendship with the girl's present boyfriend, you won't do anything, not until they break up anyway, and even then, making a move on her could make your buddy uncomfortable. On the other hand, if you really don't care about your friend's feelings and remaining friends with him, then go ahead and ask her out.
