Kind of new to all this myself but you seem to be on the same roller coaster ride as myself. One day my W is sending me TXT messages and calling me at the office just because then the next she is not talking to me. It is VERY frustrating.
Stay true to yourself - remember to have clear obtainble goals - i have tried to set these up for a week or 10 day duration - much longer than that and i loose patience.
As for his mocking your wanting to save your marriage with quotes from the book - i agree with the others - it does make me think an interesting thought - people want what they can't have - think about why you want to stay with your H. While my W hasn't done anything like that to me i put together a simple list...
I love her She is smart, caring and a wonderful mother She is beautiful - her smile is incredible and i could look into her eyes for hours She is funny and playful We compliement each other nicely and have very similar interests She is driven and a very hard worker I want to spend the rest of my life showing her that i am not a husband - i am a great husband
