Is this out of impatience? When was BD for you? It was 3 months ago? You realize that that is a drop in the bucket. Expecting your W to turn around on this that quickly is grossly unrealistic. Now I am not suggesting that you don't talk to an attorney. You should. But I would consider taking more time to decide on if you want to pull the trigger.
If you want to file because YOU want to get D'd, then go for it. If you want to file because you want to stop the PAIN, then I would hesitate. Because that won't have the desired effect.
Yes, totally agree with Steve. What's the rush, are you hoping it will bring an end to the hurt and misery? It won't. Only time and detachment will do that. Work on that detachment.
Also I noticed TXHubby posted to your thread, listen to him as well, and read his threads. His is a classic case of how placating a WAS can leave you stuck in horrible limbo indefinitely. When he finally detached and let go, everything changed. His WAS broke into full-blown panic pursuit. He was so detached he didn't even want her back at that point. I know you think you are there, but you're not just yet.
