VENTING about SO. Any ideas?

Baylie
Things are solo Stressful Rn and me and SO fought all day yesterday. 
Over everything. Which is so hard because we never fight.
We are arguing over money mostly.. We are trying to move. 
He is not happy at his Job and I think he brings it home. He's negative. 
Any ideas on things I can do to help bring him back up? 
Or maybe for us.. Something I could do for us?
