Facebook event/invite gone after I pressed "not going"?

[dwk963]

I was invited to an event about 4,5 months ago that I was not sure about so I just pressed "not going".
I changed my mind and decided to go but I couldn't find the event. I even looked for the notification but I still couldn't find it.
How do I find the event?

It's gone.....ask for a new invite on facebook or just ask directly thru the phone

Next time just click maybe, or leave it alone without responding if you're unsure

Just Try To Find The Invitation By That Person Who Sended You The Invitation, If You Find It Then You Can Successfully Change It From Not Going To Going. If It Is Very Old Then It Can Be Deleted Or Removed By Facebook Or By The User That Created The Invitation

On Search Box, type the Event that you had declined then Enter. When you find it, click the Event then ask the group to join.
