Indeed.
Chill out dude, everything will be ok. I will support you on that big problem of yours.
Maybe Ami is just having a break and some rest on what have happened to both of you.
Give her time and also yours, hang out and then if you know that it is time to talk to her, then do it, say sorry and what so ever to make her forgive you. ^^
I know Ami will probably forgive you since you both were good friends right? Oh, or even more than good friends.
