Need advice

Married 6 years, 3 kids in this span one that was super colicky, a lot of stress being “primary parent” and husband with PTSD of his abusive childhood in denial all mixes for a hard relationship. He takes care of me and the kids financially and physically and is a great worker but he has emotionally abused me so bad and always makes up scenarios in his head. Here is my question: should I stand my ground for deleting a 3 question text from a male co worker because I didn’t want the fight or accusations from my husband. I do get why to him it looks suspicious and I’ve done this one other time when an old friend who crushed me said hey I tried deleting it. I know it sounds childish but it is my first thought to save the fight for my kids sake but it has backfired. He calls me lots of mean names degrades me all in front of the kids. Am I crazy? Thanks. I can see why a lot would say divorce but just looking at others point of view maybe that’ll help
