Ill jump in as well and say I filed for D 6 weeks after I found out about OM, then 10 days later withdrew. Yeah it woke her up for a second but she was ready to move forward because she thought that was what I wanted, which it wasn't. It was a hassle and I lost a lot of respect because she now knew it wasn't what I wanted.
I have gotten much better results DB'ing and as hard as it has been to ignore the A, my WW and OM have had their share of fights so WW does see that the grass is not necessarily greener. Let him go, I highly doubt that the OW is the answer to all his problems and reality will hit them. It stinks it stink it stinks, it is the worst feeling in the world I know. But you have to try to push through, think of things that you have always wanted to do and do them. Not to get your mind off of H but to prepare for what a life would be like if D does happen.
Everyone keeps saying this limbo is a blessing to give you the opportunity to find yourself again while H is there financially and as a father to help with your D. If you file for D you will still have to get to this point and move on with your life with old H still in the picture because of your child.
I have been in this for 5+ months and I will say that any brief conversations initiated by my W and the R have taken small steps in the right direction because I have given her this space and have been GAL and detaching. She sees me moving away slowly and it makes her very uncomfortable.
I'll say it again, it hurts, it hurts bad especially if I try and dwell on it but you have to look forward, stop looking back.
