My W kept saying she was working on dissolution papers, and that it was taking time, blah blah blah. I didn't doubt that she was but she was being all friendly and texting me, and chatting me up, and so on, while continuing an apparent affair. It is a little different in that she only sees him about once a week, and it is usually to get their kids together, but still it appears to be a romantic interest.
I finally last week emailed her and said because she was continuing the affair, I was filing divorce. She said she almost had the dissolution done, so I said I would give her until next Friday.
I also am closing credit cards, moving money into a new checking account, looking into ways to consolidate loans, and all that fun stuff. I have started fixing up my house, making summer vacation plans, even re-recorded my answering machine message to say "Thanks for calling the JDOllie Family" and then me, D8 and s6 say hello, so establishing our new family.
