my husband scared the life out of me

Honey🌚 • 29. Pcos. Married. 👶🏻💙2/22/2020
My husband scared the living shit out of me today. He comes home around 9 pm from work and today he didn't. So I messaged him and he didn't reply. I tried again 5 mins later and still nothing.  next  thing you know it's been an hour. He still hasn't replied to my calls or texts. I go into full panic mode (I have anxiety) Anyways he is very good with answering right away. I started thinking of all these horrible senrios in my head. I wanted to go check up on him but I couldn't bring myself to do it. I was shaking and having full on panic attacks. I couldn't even go outside of my room to tell his mom about it. I am a super sensitive person and I start crying before I even begin explaining myself. Finally almost an hour later he replies and is apologizing like crazy.   His office is being renovated. His cousin and two other helpers were working on it all day. He was doing the flooring with them. I should've known cause I went earlier in the morning to have lunch with him. His phone has been out of Wack and sometimes messages won't even go through PLUS to make matters worse it was on silent today 😑 He comes home running doesn't even say a word to anyone else and comes into the room where I am laying in the dark just crying and panicking. He just scoops me up and hugs me and kept apologizing.  God I've never been so fucking scared in my life before. I love this man so much. I thought something happened to him. 
(((And for those of you who will start assuming ooh what if he is cheating? Don't. I know him. He won't even go to any parties his coworkers or his bosses invite him to because he says there will be other females there and he doesn't want to be around females out of respect for me. I trust this man with my life. My ex cheated on me and he knows this. He swore on his life from day 1 he would never do anything to cause me any harm)))
Has anyone ever been in a situation like this? This was the first time something like this happened. Scariest shit of my life.
