Complex #4 - D talk started / Detaching continues

[Complex]

Well...how do I deal with W leaving the house to go somewhere (at night). She doesn't look like 1000$ but hair is done, makeup on, which a while ago wasn't that usual.

So when she just left I gave her a look and said have fun, but more in a "where are you going?" tone...
Then she explained to me where she is actually going (true or not). Old work friend in town, few ppl going. Blabla. This sht makes me mad, true or not.
I obviously have trust and controlling issues still.
Should I rather be uplifting and say have fun? Say nothing? Or let her know I don't agree with what she's doing (which is an assumption, and will make her mad if I'm wrong)?
And does it make sense to apologize for making her justify herself?

I appreciate your input on this...Starsky and others
