We can quit everyday and say that we're for good and yet, we can still come back. Just like you, I've got those moments too that I quit for sometime and then comes back at random moments.
Usually, these breaks are just temporary and not a real quitting that sets them apart from gambling forever. We can always have a way to get us back in gambling.
And by the time we quit, it's only words that separate us from it but then our actions can move us back anytime.
I think we should also learn to use the words " quit" and "stop" correctly in gambling. What most of us do is stop gambling for some time and return later and it's different from quiting.
When one quits, they eliminated every bit of urge towards something and never look back.
