I lost my gut friends..Help?

Possibly one of them may like you more then the others, and he might be shy or unsure about his feelings and so him and his friends are avoiding you. Another reason is, maybe they've been too busy with other things lately, but I don't think that's the case. I would just confront all of them at a necessary timing, and ask what the big deal is. Tell them that you think it's rude and demand why they have been avoiding you (if you don't think it's rude, tell them it's mean or whatever you feel about it). I hope this helps, and I apologize for them being jerks lately. :3
