From a financial and legal standpoint, I'm covered and have already been doing what I need to do to protect myself.
But I do have a couple of questions about your responses.
About the exposure - they have already been exposed. It has been over a year since I found out and the OW has been with a new guy for that same amount of time. The OW continues to maintain a "friendly" relationship with my H. They text/email and talk to each on the phone all day while at work. H sends writes her love letters, gives her small gifts (mostly food items). Should I let OW's b.f. know?
Also, about my interactions with H from this point out. Polite but distant. I totally get. Does that mean I tell him about my future plans, even if they include S? Or do I continue to just do what I want, when I want? (Right now, I make plans, but don't tell him until last minute.)
He sometimes texts me questions about S and I respond w/in a reasonable amount of time (2 hours or less). Should I ignore those now? Should I wait even longer to text back?
He pays for groceries and I cook the food. Should I do anything differently here? This arrangement is fine with me, so my gut says leave it alone if I am okay with it.
I feel like now since he has filed, I need to do something very different than what I have.
