Listen...you want to know the truth? Because, ya know, the truth hurts.....
1. He is ready for the divorce....he is just trying to figure out how not to feel like the bad guy.
2. He is moving on....you are not (in a sense).
3. He didn't answer you because he was with someone else and he didn't want to answer about it to the other person....stop me when I lie.
4. Notice it is all "He" so far?
5. Stop calling him....if...and I mean IF he is even remotely thinking about you, the constant repitious calls are only re-enforcing his decision about leaving the marriage.
6. How do you think this is all rolling???? In what direction...
Look, none of this is fun....this all sucks...look to religion, a friend....whatever you would like to do. BUT! Look at in this perspective....look after yourself and your interests...don't get left out in the rain....or the dark...or whatever...
Point is, be prepared, look out for yourself and stop worrying about trying to get in contact with your soon to be ex....plain and simple.
