Rouky, There are any number of reasons why he may not have filed. I'll name four that come to mind: 1) it takes a lot of time and money to file and he doesn't want to do the work; 2) he's waiting around so that you'll be the one to file and then he won't look like the bad guy; 3) he doesn't want to use the "I'm married" card so that he doesn't have to commit to the ow, i.e., engagement and marriage, and 4) you are Plan B just in case things don't work out w/the ow.
He could be nice right now because you aren't rocking his boat about financial stuff and he may be hoping that you'll stay right where you are and not make any time of trouble for him, i.e., money, separation, etc.
Why bother writing about him? You need to get your thoughts out on paper and this is a safe place to do so. Trust me, you have to let that steam off somewhere and this is a good place to do so.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
