Are you considering this because you're hopeless for the marriage?
Are you considering this because you're tired of being in pain and think this will bring an end to your suffering more quickly?
Or are you considering this because you truly believe this is the right step to take to best stand by your marriage?
IMHO anything you do within the first 60-90 days is probably rushed. You are too emotionally unstable to make life changing decisions. I compare it to thinking you can still drive after having just a few. I'd encourage you to slow down.
Yes, you can stand up for your boundaries at some point. Yes, there will be a day for action. But this seems very fast to me.
Can you get a DB coach? I'd highly recommend one. And until you do, I would be willing to bet they'd say the same thing I'm telling you.
