What Lisa said - that's a decision that no one here is qualified to make for you, but it's definitely a tough one. Have you thought about seeing a therapist? They can help you work through things to figure out what you really want and what the best course of action is. A good therapist won't influence you, they'll just help you to make the decision yourself.
I eventually decided to end my marriage. I gave it some time after leaving the cult to try to make things work, but it went downhill fast. From your tone, it sounds like your wife is handling things in a much more measured and respectful manner than mine, which bodes well for you. You'll have to figure out what sacrifices you're willing to make, though. I couldn't keep going to meetings and I didn't want to live by the cult's rules. I wanted to start living a normal life but my wife would never support me in that and was only negative about anything new I did.
It'll probably take you both a while to settle in to the new normal, whatever that is. Once you start to see what that looks like, you'll probably have a better idea of what you want to do.
There's no need to rush this, just be honest with her and yourself and it'll either work or it'll start to become clear that it's not going to. Good luck!
