Marriage and pregnancy..venting

I’m 16 weeks pregnant and the stress has gotten to my husband :/ he’s so overly stressed about everything and often forgets that I’m stressed too. We agree on everything but the stress has gotten him on thin ice. He isn’t motivated to do anything, not even work or college. It’s affecting our relationship... I communicate it and discuss solutions with him, but it’s only adding on stress for him... so I thought maybe distance will work but it’s only making him struggle alone... I’ve tried pretty much everything to motivate him and take the stress from him but I just can’t :( I don’t like seeing my king stressed or in pain
