If this, "You know he/she appraoched me and asked me out..." is not true, then both of you (you and your friend) can adore this hell of a cutie.
i love mine bruin jan, you know that you are talking kaka. The friend doesnt necessarily have to be a close friend, but someone you know and trust.
Does the friend have a right to be mad at you or are you at fault for dating someone that you know your friend is interested in? If it's not a very close friend then it doesn't matter as much as a close friend.
It's a good idea to drop a few subtle, flirtatious hints, but the most crucial move of all is to invest in some one-on-one time.
If you usually hang out in a group, see if they want to meet up beforehand. Ask if they'll pick you up or give you a ride home.
