I hate going through this

This afternoon I dropped off my husband at the airport for his 3 month deployment rotation. I cried the whole way home. I cried in Ross during shop therapy. My son was waiting for daddy to pick him up from daycare, give him a bath, and storytime. Hes going to be walking around the first month asking were daddy is. Our big dog won't leave the front door because he expects him to walk through it at any minute. My heart hurts so much and it never gets easier.
