Your husband suffered with separation anxiety, caused by being left alone all the time as a kid as a only child.

You had snuck out while he was asleep,going to get some snacks.When you had returned you saw him slam the door to you house.Dressed and with glasses on to hide his red eyes from crying

He froze and quickly ran over to you,wrapping you in a hug as he swore angrily under his breath.Letting out a sigh of relief none the less.
