What are the clues you have to him cheating?

Try and catch him out keep track of everything he says and remember it and he may say something else later.
Also how often is he leaving you to this 'emergency' or that
Hope you find what you need!

sorry to hear that.
If he is cheating he has ,no matter how hard he tries not to, left a trail of evidence(phone,creditcard,internet,paper recpt..)
If he is lying cheating jerk you can take him down matlock style.
Hopefully you are wrong though.
best of luck JJ

If he's cheating you'll have a true gut instinct. Follow that instinct and find out.

Or just lay your head on his chest right where you can hear his heartbeat really good and ask him if he's banging some other broad and if his heart starts racing, he really might be, if it's pretty much the same he's not.

Listening to heartbeats works great :)

I can tell you how I found out. I purchased net dectective, which tracks everything he types and also video. They have no way of knowing its on.

Does he keep getting texts?, does he keep his phone with him at all times?, is he 'working late' alot?

Those are just the obvious ones.

Also, men find it hard to lie, if you look him in the eye and ask him outright, if he cannot keep your eye contact, looks away - there could be something up.

Look him in the eye like Avalanche said, and listen to his heartbeat while asking him a question, this really works!

People can't look you in the eye and lie without a facial movement. They twitch, blink or open their mouths a bit and sometimes bite their bottom lip. It's weird, but it's true....i read true crime, these are signs of lying Detectives look for! lol

well socal... on the most part that is true, but some ppl are consummate liars and have trained themselves to be able to do it and convincingly so. They learn what the "tells" are, and work to eliminate them... so, if your S/O is a regular person, then yes this works, but if the are a con-artist... then well... you will have to go to other means.

eww. i feel for your situation and how intuition or fear can drive assumptions.
first, have you asked him?
also knowing what it is that motivates this discussion/advice area would help us better understand your situation and why you are questioning him.

thanks guys hopefully i am just trippin.

You could do some totally unexpected things - like turn up at home when not expected (10 mins after you have set off for the shops is a good one, cos he'll be phoning her)

Or take a peak at the car mileage and see if it is consistant with going to work and back. Of course there is no saying that differences are not totally innocent. But if every single monday, wednesday and friday the milage has doubled, then you could ask the odd innocent question or request the car on that particular day for yourself and see how amazingly impossible it suddenly turns out for you to have it etc. etc.
