Should I leave - husband on grindr

I discovered grindr in my husbands search history. When I confronted him he broke down and told me he was raped 16 years, he has downloaded grindr in the past when intoxicated or high. He's never posted photos, spoke to anyone or met with anyone, he would sit and scroll, he doesnt know what he was looking for on it, or why he would download it. The next day he would be full of disgust and regret. He has lied to me in the past about drug use and gambling. He started to see his therapist again who has diagnosed him with depression but he wont see a doctor. I dont know if I can get passed this, is it more lie's.. im feeling sympathetic because i know people have different trauma responses.. I still look at it as cheating... Do I leave him ? We have 1 child, together 8 years.
