I know that you are still in the same house, but I think that it would be beneficial if you set up a schedule for who is responsible for the kids on what time if you have not done so already. The schedule can remain flexible. It also eliminates the last minute texts asking for you to watch the kids.
For example, my H has the kids Wed/Friday nights. It allows me to book things in advance. On Wed nights I go to IC and then to gym/yoga. I can make plans with friends on Friday nights and/or run errands. Next week my H had a conflict, so we switched Friday/Saturday night in advance. His conflict actually fell through, but we kept the switch since I made plans in the meantime. Although we are flexible, there are no last minute texts asking to cover the kids because a happy hour came up, etc.
This allows you to GAL. It also eliminates the last minute texts asking for you to watch the kids. It will also help you feel like you have a little more control over the sitch instead of waiting to see what your W is going to do/plan.
