Daybyday, your WH still loves you. How could he not? I know it's hard to think that someone could love 2 people at once, but remember his love for OW is "adolescent like"..."luv." And he has 20 years of history, family and mature love with you.
Keep doing new things because he thinks he knows you inside out, so surprise him. Your kids will mention it and it will be on your facebook page.
Shock the hell out of him by doing what you're doing--not reacting. Not chasing. Appearing strong--"Oh Well. I am not done living my dreams. Going to take these classes and meet new people (I LOVE that about college). I will be okay; I'm an attractive, confident, interesting, nurturing, talented woman and am very capable of meeting someone else."
Inside, you may be feeling the opposite but keep repeating this and you will believe it. (it is true though!)
Have you seen the movie, "The Women?" With Meg Ryan? Watch it--her H leaves her for an OW after 15-20 years of M and you can be inspired by how she handles it. It may hurt in parts but has a good message.
