Are you saying that you feel your W is on edge about you serving her papers? Please, please, trust me she knows there is zero chance right now and to be quite blunt right now she would love it if that happened. Years down the road she could tell your children that you filed for D.
I wish there was a way we could convince you that if you move out it may be the biggest mistake you ever made in your life. If her main goal is to reconcile, why does she have a name and number of a lawyer already.
I lived in IHS in the end for 15 months and it wasn't that stressful at all. Kids I don't think even really knew anything was wrong. Have family dinner together then went our separate ways. We even started having sex again the last 7 months until she left.
The key is to drop the rope and accept that it's over. If she starts moving toward and making and effort then you can reevaluate. All the BS she fed you last night we have heard on here 100s of times and I think Steves is the only one that turned around. He DBed 100% by the book and if he would have moved out he would be D by now.
Remember reconciliation is always a possibility. My friends parents got back together after 35 years.
