This story happened years ago.  It was just a few months or maybe about a year after we got married, we bought a new house and moved to another part of town about 30 mins away.  One day I came home before my wife.  I noticed she came home, and pulled her car into the garage but did not come inside.  But instead she was in her car talking on her phone.  I didn't think anything of it.  But nearly 1.5 later, she is still on the phone in her car in our garage.  So I thought maybe something important happened and she's talking to one of her family members.  She doesn't have many close friends so usually if she's on the phone its with one of her sisters or family members.  I thought that this was the case.  I went to go check on her and see if everything was okay.  As I approached her car, she abruptly hangs up the phone and exits the car.  I ask her if everything is okay and she says yes everything is fine.  She was just talking with "a friend".  I didn't ask who and didn't question her further.  The Friday comes around and she asks me if it's okay that she goes out with some fellow coworkers after work for some drinks at a nearby restaurant.  I'm thinking sure, it'd be cool for her to have new friends and go out occassionally, no big deal.  So she goes out on Friday with her coworkers.  But then 3 hours go by after she gets off work and I don't hear from her.  So I call her to see when she's coming home.  She doesn't pick up.  Another hour or so rolls by, still nothing.  So I call her a couple more times and leave her messages and texts... no answer or text responses back.  Hours later, she finally calls and says she will be home later and she didn't hear my phone calls.  I thought okay that's reasonable I guess.  When she finally comes home she is halfway drunk and horny.  She says next time she will call me before coming home so I'll know she's safe.  Next Friday rolls around, and same story, no phone calls, no responses to my calls/texts.  Eventually Fridays turn into a regular thing now.  Our sex life at home become more adventurous and she starts to suggest things we do sexually... something that has NEVER happened!!  And she starts to suggest new positions, fucking her in the shower, more blowjobs, and even swallowing me more!  I start to wonder where her new sexuality comes from and all these new sexual ideas are from.  We have been together for a while before marriage and she is NEVER the type to suggest anything sexual much less new sexual positions!  So I check out our phone records and notice that she has been calling and texting a number all the time.  But I have never seen her calling or texting this much around me.  So I call the phone number and found out it was one of her male coworkers.  She has been talking about him but I never even noticed.  She would tell me that he is a pervert and is always talking sexual stuff at work around other coworkers and her.  And he was the guy that she was calling and texting behind my back?!  It was even him that she was talking to that day in the garage for almost 2 hours.  She is also becoming more secretive about her phone saying she needs some privacy.  Also, she starts deleting all her texts back/forth to him.  Being secretive about her phone and deleting her texts is something she never used to do.  So I confront her, and she denies they are anything but friends.  Weeks go by and I confront her again asking her if she is cheating on me.  She says no, but admits to being attracted to him.  She even asked me if I'd ever be okay if she dated him if I'd ever be okay with that to see about her feelings about our relationship.  She starts getting up earlier for work and begins to wear sexy thongs to work, new lingerie and thongs that I have never seen her buy show up.  She comes home Fridays super late, usually around 1-2am.  She is giving me more blowjobs and swallowing my cum more than usual.  She is coming up with new ways for me to fuck her.  So I finally tell her she has to either change jobs and stop contacting this guy and choose between our marriage.  So she switches jobs and stops going out on Friday nights with her coworkers.  Life goes back to routine, as does our sex life. 

So what do you think?  Do you think she was fucking her coworker?  Or was it just an emotional affair?
