Nicole, mine has been telling me for years he wants a divorce. I have been trying to get him to sign a separation agreement (a custodial and financial settlement) for over a year now that can become the terms of our divorce after the 3 month waiting period. To date he has not filed or returned a single comment to the separation contract. He has now been with OW2 for about 10 months I think. I called him for the first time in 6 months to try to instigate a divorce conversation (which I want but my lawyer advises me not to file because of my situation). I asked repeatedly if there was anything he wanted to discuss, anything at all. He said no.
He may want a divorce, and he may file, and he may see it through. But there are so many stories of people like my H or the ones who start the process and never progress it.
I tell you this not to give you hope (and I think yours sounds like a much bigger dirtbag than mine) but because I don't think him saying this changes anything about your situation. Go on and do what you need to do for you and your child and stop worrying about what he is doing (other than protecting yourself financially).
