Help

Sorry im confused as hell and cant make a decision. Wife and i have 3 kids, no cheating, no abuse. Weve grown apart for years. Have slept in separate bedrooms and no sex for about 3 years. She is extremely anxious and her and my oldest fight constantly, he comes to me breaking down, and i try to meditate while supporting her... But she is extremely hard on him. Everything is worst case scenario, she thinks ive cheated (i havent), but the final straw was i sought counseling i make sure i couldnt do anything better. I found a female therapist for her point of view on things. I told my wife in the beginning but apparently she didnt realize i was seeing a female one. Well, a couple months later she found out it was a female around our age and lost her mind, basically blaming me. Obviously i never cheated. Not even close.

So last 4 weeks we were agreeing to divorce and she saw a lawyer, but now shes turned and is hysterical that she doesnt want a divorce, the family is being torn apart, and wants to keep trying. We tried to console each other last night and it was just awkward as hell. Im 95% sure i want a divorce, but am too chicken to make a mistake. Is anyone ever 100%? I cant sleep and dont know what to do. I really dont think i can think of her the same. If she has these reactions over me seeing a therapist and thinking im cheating?? For context, i work 2 jobs to provide for kids, never go out, never hang w friends. Totally committed to family. I just feel like theres no good in any of this. Help...
