You are no longer in constant crisis mode. You are starting to very slowly adjust to your new normal. You are probably experiencing alot of "firsts" such as overnights where kids are at their dad's house. Maybe you have to see your ex at an event for your child or your ex has a new partner and wants to introduce her to the kids.

You may also need to consider court, child support, attorneys, etc. which is always stressful.

You aren't in the constant emotional crisis that you were in Stage 1 but your heart may have a hard time accepting what your mind already knows. You may feel alot of sadness in this stage that can turn into anger quickly. Especially, when thinking about how your ex moved on so fast, or how he doesn't seem to care about your feelings or the time you spent together.

Your kids are slowly adjusting to their new normal as well.  How the do from this point forward has alot to do with how YOU are doing and handling things. It is important to remember that your kids feel your energy, they are very in tuned to what's going on. Many times he is either not involved as much as he was, even if it through no fault of his. Going from waking up to the both parents daily to not is a huge adjustment for them . 

You are left in charge of picking up the pieces for your kids with this change.

Compared to Stage 1 you're starting to be able to focus more and you maybe having moments where your thoughts aren't consumed with your ex and the split of your marriage/relationship. But thoughts of the past, your ex, how you will handle single mom life, and what your life will look like moving forward are often.

It's still an emotional rollercoaster and you are most likely triggered often by dealing with your ex and trying to co-parent with the person you are trying to heal from.
