Has she given any reason over the course of your relationship to think she has cheated on you?
If yes Dump her
if no, Trust her.
Dont ask if she hooked up with anyone - these questions are different for males/females
If a girl asked me, I would simply say no, and put it down her to being insecure and move on. I would reassure her and ti would be all good.
If you ask a girl... You show neediness, a lack of trust, and insecurity, all things that are unattractive to women.
She couldnt simply be pissed off she isnt on holidays anymore, or she is back at work, or whatever... Just give her a bit of time to get back into her routine... She could have jetlag or whatever. There are a million reasons. Dont let it get to you. Relax and enjoy the fact your girlfriend is back, and that you get to have sex again... Dont fuck it up because you are insecure :P
You are more than likely reading into stuff that isnt there as well. As much great advice that TAF gives to people, and how much it helps them. it also fucks with there head and makes people read into shit that isnt always there.
I spent a lot of my money on booze, birds, and fast cars. The rest I just squandered.
