Hi Chicken Soup,
Thank you In_n_Out.
I've asked her to go to counseling before, so I'm not holding my breath. This is the first time I've mentioned divorce.
I've had practical reasons for not divorcing her yet - I would still have to deal with her (two teenagers under 18) and finances.
If I'm serious about this, I need to talk to a lawyer. And read the boards here.
it is good that you are getting serious about making changes. Keep in mind that there is a thin line between being assertive, being passive aggressive and issuing a threat. It may be good to review DEARMAN for how to do strong pushes for what you want. If you want to go down the couple therapy road maybe it helps to become more concrete on what you have in mind with reasonable levels of commitment expected from her.
