Please help should i go visit who i thought was my best friend? HELP PLEASE?!?!?

If you planned to go with the Youth Group and you still would like to go to the retreat, then go on your own. You don't HAVE to go WITH her do you? You can go on your own and just meet her and laylay there. As it's a group you used to belong to there will be other people attending who you already know and I'm sure they will be pleased to see you and find out how you are getting along so you could hang out with them instead if BF and LL give you the cold shoulder.. Just because your ex best friend has made a new friend of this laylay girl, it doesn't mean that you can't be friends with her too or that you have to follow them around like a little dog. It doesn't mean that you can't have any other friends either. You've moved away and you have both moved on. Don't be unfriendly with the pair of them or expect bad things from them - just be your usual self - but be independent and make other friends while you are there. You are concentrating too much on this one girl who used to be your very best friend. Sadly, she sounds rather childish to me if she's blaming you for moving away when you had no control over that situation so I think you'd have probably outgrown her by now anyway even if you hadn't moved away. Just be pleased to see them both when you meet up again and be pleased to meet all the other girls too. If you are open and friendly with people, they will want to make friends with you. If your ex and her new g/f want to remain aloof, just accept it. Don't show that you are upset about it. Just carry on as normal. If anyone is going to look stupid it will be them because you'll be the most popular girl at the retreat. Enjoy yourself.
