Finding out you bfp

Hi ladies, I see a lot of posts on here that asks the question 'how do I tell my husband I'm pregnant?' Now, as far as I am aware it is a journey from ttc to birth to the rest of the child's life, so, why on earth would you take a test when he isn't there? Surely he should be finding out the same time as you? I peed on the sticks and he looked, joint decision and finding out together was amazing! So why do others take the test without him? Baffles me!!
