What to do when an EA involved?

[Hoju]

Having an exceptionally rough night so figured i'd post instead of doing something stupid.

Wife never came home last night which i've been slowly coming to terms with, giving space and such. However when she came home today her clothes were caked in mud. She never ever wanted to go camping with me much less ever get dirty, i couldn't even convince her to come to a cottage with sime friends because she was so insecure about going without makeup and pooping. Is it possible she has really changed or is this just a front to impress someone else? I know it doesn't matter and i can't change her actions but writting this is all that is stopping me from going upstairs and asking about her weekend and where she was.... Also asking why she never wanted to do anything with me.
