When to tell DH about BFP?

My husband is so bummed every month when we get a BFN so I'm thinking of taking him our of the loop. He takes it really hard and is super mopey for a couple days and I'm think when we do get a BFP to keep it quiet and test to confirm in a couple days. If he is so upset over a BFN I'm thinking he will be devastated over a chemical or false positive. Thoughts?
