To Pursue or Not

[Arcola]

I need some advice seasoned DBers. My W has started working a 2nd job and as of the first few nights come home later than what she she'd normally come home (she's had this job before, its seasonal). Anyway I feel some things up with her and OM. Moreover her taking this job again was supposed to be a way for her to have more money to move out. I really have no problem with keeping our 5 kids so she can go to work, but I'm feeling used when she can't come home after work.

I want to do something, but don't know what. My job isn't so flexible with me just working 8 hours or getting the job done and still making 40 hours in the course of a week. So with that in mind, what are some things I could do to take action towards this behavior?
