WHats your opinion on this situation?

It seems to me that you want Aimee all to yourself. You need to let her be with other people too. Also when you said that Aimee invited Janine everywhere, it's fair and not fair. It's fair because like I said she needs other friends, not just you. But it wasn't fair because she was your friend and she hung out with you and then she pulled Janine along without asking you. Let's go back to the first thing I said. You wouldn't think it was fair if Aimee came back from Texas and didn't like it because you hung out with Morgan. So you need time away from just Aimee just like Aimee needs time away from just you. Believe it or not I had the same problem with my friends too. I hope I helped you.
