WH, I'm glad you and the kids had a very nice weekend, boy it was a busy one! I'm sure the kids had fun at the pumpkin farm. I always love doing things like that. The fresh air, excitement of finding just the right pumpkin and the hayrides are the best. Good old fashion entertainment.
God has a way of putting people in our paths to help us see things. For example, the lady from your church spoke to you and identified your h's issue to the "T". There are more people going through the mlc than you think and as you walk the path, the doors will open and God will ensure that you speak to more who have gone before you that have experienced mlc. This will help to open your eyes more and make you even more wiser.
As for what your h sees in the ow, well...it's something "new" to him. She's the exact opposite of you, so that's "new" to him. She's got health issues, he wants to rescue her. She may boosting his ego and telling him things that she knows he wants to hear. Also, the affair is new and exciting because there are no responsibilities associate w/it just yet. They are both on good behavior right now, but when the divorce goes through and they are together 24/7, those nice little goody masks will begin to crumble after a while and the real people will emerge. Now, that's when the fun will begin to fade.
No, she is not the better person here...but in his mlcing eyes, he thinks she is. Anyone that is having an affair w/someone else is not the better person in my books.
Hang in there.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
