I am really struggling today

When I was 14 I met the man I knew in my heart was my soul mate. He was everything I hoped to be in life and the person most aspire to be. When I looked into my future he was there. He became my best friend. We talked every single day sun up to sun down. A couple years later he went to college. He was studying to be an anesthesiologist. One day he was watching tv and he literally fell over dead. The autopsy came back that he had ARVC. We didn’t know. No one, including him had any idea he had a heart condition. I still remember when I found out. I was laying in bed it was late and I got the message. Everything stopped. I swear I could hear my own blood running through my body. I couldn’t feel anything and felt everything all at the same time. That was 7 years ago. I am married and have two little kids now and today I woke up with so much pain I could barely get out of bed. My husband and I had a fight last night and he told me I could win a “bitch of the year” award. Alls I can think is he would have never talked to me like that. I feel horrible because I’m thinking of and grieving this other guy when I’m married. I’m just really hurting today.
