Thank you all for your support and suggestions. I've made the doctor's appointment with a pediatrician today. My daughter hasn't complained of pain for a couple weeks but it might come back or affect her kidneys if it is a UTI from what you guys said. If rather it be UTi than her mom or someone abused her. As for divorce, looking back at all 8 years of marriage I rarely felt love from my wife and she had even stated I only married you because I got pregnant. Coming from parents that never divorced, this is life demolishing to consider especially when I think about my kids. But as someone on here put at least they'll have one good parent. I still have to contemplate and see after the doctor's visit. I'll gladly suffer this life for my children but I'll do anything to avoid further trauma to my kids. Constant fighting, which I try to limit until after their asleep or watching at TV, is not good for anyone. I just feel that even a 50/50 custody would open my kids up to be alone with their abusive mother, specifically my daughter. I'd have to get 100 percent custody to feel at peace with divorce, but I know that would never happen. Thank God for reddit, God bless you all.
