Stuck in jade tower

[Damian]

well since all my Pokemon fainted in the battle with the auger I had to go through the black market again i thought I was gonna respawn next to Chansey but I didn't....I went back to the jade tower and Damien was blocking my way and I went back but it says you can't leave now and after that I stupidly saved and going back doesn't work anything anymore I can talk to Damien and check my menu and I have tried everything like escape rope but it doesn't work....it was really hard getting there and I don't wanna reset my game since it was sooooo hard leveling up my Pokemon and I love this game soooooo much I honestly fell in love with my Pokemon and I don't wanna reset is there a way I can go back a few save files and btw I have a mac
