Me and my friends have a group and we play music... I love playing music and I don't want to stop this... a month ago.. we decided to make member of our group a girl one year older.. the girl agreed and now she the singer of the group... the problem is that I liked this girl a lot before we ask her to join our group... Now I would love to say to her what I feel about her but if she doesn't want to be with me she will leave the group and it will be my fault.. the other members of the group know that I like her but they think that she doesn't seems to like me, she sees me only us a good friend(they say).. one of my other friend at school says that during the interlude he is watching her and see seems to look at me all the time.. and he thinks she likes me... I am confused... please somebody help me...

Wouldn't it be simpler to ask her out on a date of some sort and see how she responds? She very well may have a policy of not dating people she "works" with.

I don't know why you have to tell her how you feel about her (which appears to be that you like her) right now.
