The wheel is now badly compromised, if you continue to ride it, it will make everything worse. If the rim is actually in good shape now, it can be rebuilt but if you pop more spokes while riding on it, you could pull the rim way out of whack and make it not rebuildable.

I'm a big guy as is my son so I might be overly cautious but I would rather err on the cautious side rather than the side of recklessness.
