Hey Jim, sorry to hear about you not having a good time at the Christmas party. I know first hand how hard it can be to hold things together on a good day, add a few drinks, the Christmas season and people who don't know asking about your W. It's really no wonder you broke down.
Like many have mentioned it does get better, the highs aren't so high and the lows aren't so low, thing do eventually balance out again.
Not sure if you've decided to file or not yet but has your W indicated to you that she is going to file or was this all mind reading? Sorry if I missed it but does having a fault divorce really add that much to your case? If not why do you want to do the work for your W especially if it's not something you want?
At the end of the day you need to do what is best for you and your kids. Just make sure with what ever you decide it is best for you and you aren't just looking for a way to try and punish your W or out her for her bad deeds.
