No no no--your DH is dead wrong. We've all fallen learning to ride clipless. Think I fell once or twice--and then had a banner day when I was trying to learn to stop with one foot still in (secret---step down onto that clipped in foot and forward off the saddle, and then onto the unclipped foot, and don't lean towards the clipped in foot), and fell three times, got good and bruised as did my bike. And haven't fallen since (it's been many months). Keep it up. You'll get it.
