Answer:
They may want time to be with their other friends. I know how this feels and it can really suck some times :(. It wouldn't be the best thing to confront them since it could make them feel pressured, instead you could try expressing your feelings to them and telling your friends how you feel :D it can be really rewarding since it feels good to get things off ur chest TvT also, real friends don't do that! If they wanted to be your friend, they wouldn't ignore u. A friend is someone who should be able to tell you the truth, and they would've told you by now why they were ignoring u :cc
