Bro, I know the PTSD thing [censored]. If you want out of the relationship, be 100% sure about it. If you are, sleep on it and then think about it again.
Then sleep on it again.
This isn't a dating scenario. There's a kid involved. You're married. Not that divorce is permanent, but it is a huge thing to tackle. Divorce can change people, and make them act in odd ways. It's very stressful when you're going through it.
But it may be what is best. It just depends on the situation, and only you know what's best for you.
