k this is a little bit strange question but I am getting this problem lately I am getting the approval(I mean most girls like me in 1 set)but there is 1 girl that does not like me

First time it was 1 set of 4 girls 3 girls liked me 1 girl did not like me but they were all as a group there that is my problem my fear is that if I do not get approved by the whole set I am thinking that I must eject my self.
And this has occurred more than 1 time to me.To get approved by the most girls in the set but not by all of them.
And in order to be more clear the 3 girls were happy speaking to a guy they did not knew
they were dancing with me but there was 1 more girl there so I went and spoke to her also cause she is part of that group I was polite with her << I said to her hello I hope I am not bothering you but since I met your friends its good to say a hello also to you>> she said<<leave us alone we are girl group>>
Sometimes the situation might be different but I believe you understand my point
Is it good to continue to run my game in situations like this?
Will it be good to ignore the girl and continue or just say to her well look you might find me annoying but some other don't.The thing that I afraid is that girls are girls you know they are a group they are not like us that when we find a girl we like we forget about our mates
