Good job at the 'shockandawe'! You have his attention.
You have admitted to some flip flopping. It gets hard to stay focused. It really helps in sustaining results if you KNOW WHAT YOUR GOALS ARE. What do you really want between the two of you? What do you really want for yourself and children?
Make your goals
1) realistic (do you want him to be completely monogomous (sp)? This may or may not be realistic with him
2) simple (doable in the next two-three weeks)
3) positively stated (state what you and he will be doing or what he will be doing -- NOT what you DO NOT want)
4) action oriented -- (verbs)
5) concrete, clear measureble--how will you KNOW FOR SURE you've reached it?
