Read DB and DR, commit the ideas to memory. Do the 180s, GAL and at the same time think about what he might be getting out of the other relationship. It may be that he feels she's a great listener and strokes his ego. Try doing this yourself. Don't mention MLC. Be positive, smile a lot, be encouraging, don't criticize, and just agree with everything --whatever crazy thing he says. Ask lots of impersonal questions (like a friend) and listen listen listen! When he's with you make it all about him so he feels special. Regardless of where the marriage goes, this will help you in any future relationships.
Even if your heart is breaking, go out with friends, GAL, buy some new clothes, sexy stuff, do your hair, make-up... do things that help you feel good about yourself. Sign up for a class you've always wanted to take. Start focusing on you and working towards becoming an amazing person. Try to have some fun.
There is no arriving, ever. It is all a continual becoming.
