Stroke and heart survivors caregiver

Hi all, my wife had a stroke 25th august and week later open heart surgery to remove a growth, cause of the stroke. All was going well 2 weeks in after being back home. 8 weeks later she walked out of our family home. She is now back home and with all the love in my heart, i am working to save our marriage. This occurence brought up all issues from our past which i am saddened to admit including controlling behaviour. I am now getting help via councilling.She is adamant that i stopped loving in her in the 8 weeks, but making her believe that i do love her is hitting a brick wall. I did get stressed with her and 7 kids to look after and i quit my job to be there,  so was financially worried also. I threw negative comments at her and caused arguements. I was scared of being in a carer/ patient relationship which scared the hell out of me. I am soo grateful to have her back home, but worried that all my actions in those 8 weeks have ruined my marriage. I love her, truly deeply, she was and is my one true love, but im on edge every day whilst we are living together as friends? I miss cuddling on the settee, simply holding hands ect. Any help, critiscm - i sure feel i deserve it. Or positive comments will be greatly appreciated. Many thanks
