Our lass is really doing my nut in

Ever since she started her new job, shes been doing lots of "overtime" in the evenings at the office etc, mostly when ive been working on an evening etc. Anyway was round there this afternoon and she was like "oh forgot to tell ya, im working tonight" (she always keeps tuesdays free as its one night i never work)

Ive thought something dodgy for a while, so anyway I parked round the corner about half 4ish, ready for her to leave to get to "the office" at 5. 5.30 and still no sign

Did a quick 3 pointer and went back round to the other side of her road, where theres a clear view of the house (trying not to drive down her road to make myself known ) noticed her car was still on the drive, and a silver Civic parked on the side of the road outside. Yet shes still texting me as though shes at work?!

7pm comes and she rings me, she sounds a bit shaky/as though shes upset, starts saying she hates confrontations and that work have asked her to work christmas when she said she didnt etc etc. Strange? So did a quick blast up the road to her house, her car STILL ON THE DRIVE, yet no silver Civic on the side? She then says that she isnt going to be doing overtime tomorrow night (even tho shes already told me she was gonna) Seems strange huh?!...as though her and this fella have had a barny?

Anyway, half 8 comes, "im home now, got out a bit early" bla bla bla, anyway didnt go round coz as you can imagine im a bit pissed at this point. Other thing that gets me is that she always texts her overtime hours in to "Paul" at the office who is supposedly her new boss.

Anyway am gonna ask the slut tomorrow gonna have to be done as its gonna nag etc even if it is somet innocent (doubt it as she acctually needs to use the car to get to the office ) but what you guys reckon?

Am i being taken for a fool or ya reckon there is a reasonable explanation? I say the former myself...
