WAW - is it too late?

[RVM]

I should qualify this - I'm more concerned that she will paint a bad picture of me to others (family, friends) because she doesn't know what I'm doing at night. I've already witnessed what she's capable of saying when I'm right there in the room. She knows I'm extremely suspicious of her behavior and has been on the defense (or attack) ever since I confronted her about it months ago. My mysterious nighttime GAL'ing might be more ammunition for her to paint a bad picture of me.

For example - and this has happened a couple of times - when I've told her I'm going out with no details, she's directly asked me:

"what do I tell the kids because they'll ask?" or

"what do we tell our friends, they'll ask?" (if in a situation when we were all invited to friend's)

Since some friends sense there's issues in our R and likely my oldest D does to - I'm a bit sensitive to how I may be portrayed in this sitch. These people don't know about her awful behavior, yet.
