Help me please....FH is going to be so mad at me :(

So the other night he gave me his debit card to go buy some stuff , and I thought I gave it back to him.

I just found it in the dryer in one of my pants!!!! IT's a little bent on one corner.

Can the bank do anything about this before we go on our HM on monday????

Please help...I am so stressed out now that its down to the last minute here. :(. It's not like I meant to do it on purpose. What can I do?????

Any help would be appreciated.
