You can still comfort him, from afar, which is better than OW, she is probably drowning him in bleck. What a weird and yes, draining day. From one thing to the next. But look at your day:
You are:
1) Seeking help for yourself (something your H won't do right now)
2) Gainfully employed with good work ethics
3) A very good mother, who will drop anything to take care of your kiddos.
4) A supportive wife and friend (offer to support H even when they do the things they do to us).
Once again, BETTER person, working on getting even better. Way to go!
