No, that's not who I want to be. The thing is, I have a very bad temper. I was once married before and my temper would get out of control on the regular. It ended up costing me my marriage because my wife wouldn't take it anymore. It took a couple years of therapy but I have found peace. Since then, I have been less confrontational and my current wife may have take advantage of that. To answer your questions again, no, I don't want to be a cucold. I really don't want to go through divorce again but it seems that may be the only way.
You're saying no but your not meaning it.
You don't want to be her cuckolded husband, but you don't want to go through divorce?
"it seems that may be the only way." Noncommittal and wishy-washy sentiment, won't work thinking like this
You keep that attitude up you as good as got a leash around your neck already.
If you're not 100% and with you being non confrontational, you may say you'll file for divorce, but she'll just lure you in with sweet words and a few nights of good sex.
She'll then have you even more around her finger than she does already, and then a few weeks or a month down the line her Bull(cuckold term) will be coming back for round 2 expecting you use your back as a landing strip again.
Get out of the marriage, thats all there is to it.
No separation, no "I need space"
Call a lawyer, and listen to what the man is saying and then file.
