At this point, you will know in your heart what decision you believe you need to make. It won't be a matter of listing pros and cons; it will be a matter of knowing what decision is the right decision for you.
If possible, don't share it for a day or two. It will continue to be at the top of your mind, and you'll have the opportunity to consider the consequences. What will your partner think? Your children? Your other loved ones and friends?
Remember - it's your decision, not their decision. Think about how you will respond if they argue with you or voice their opposition. How will you explain that it's the right decision for you?
