Thumpered, yes I didn't think I would get an apology. But this was one of my conditions for returning home. Regardless it was a true apology, not just to come home.
The conditions to come home were to tell me what she did, apologize, boundaries on relations with OM and going out behavior, and transparency (FY suggested this). Since she agreed, I said yes come back.
BTW, she was worried whether I would take her back or not. Her Mother is living with us, and I think my W got the message, "hey, he's fine without you." I wasn't an emotional wreck, and I did everything that needed to get done, including buying a b-day present and sending my two oldest off to a sleepover b-day party.
My W will likely start pushing the boundaries, probably not for a month or so as she get comfortable again. IDK, I'll see what happens.
MLC changes the person. My W will not be like she was before. I can see that a new permanent part of her personality is going to be seeking excitement and adventure through sports/hobbies/activities and also having a very active social life. Hopefully it will come into balance and not be the dominating focus of her life as it now seems.
