Imagine the worst case scenario and you ultimately divorced him, or what if he had passed away. How would you move forward with your life? Start doing those things (minus establishing a romantic relationship.) Don't feel like you to include him. Pursue new friendships and hobbies. Find a therapist to help you cope. Work on you! Go visit your children by yourself. Go on a weekend trip with your neighbor to test how you'll do together, or even lunch and a spa day. Live your life to the fullest. The rest can be dealt with after he has more time for recovery and you're in a stronger place. Give your self permission to focused on your own happiness for now.
