what do you think is going on?

well,u mind is already made up and we can really tell coz we getting ur side of the strory only and from wht u saying there is something at work thats making him happy.

well, if i were to jump to conclusions i would say he`s having an affair. i mwan specially if he works in an office, and comin home takin a shower. you can either, ask him out right or wait and try and catch him. look for things like, perfume on his clothes when he gets home, if you have accsess to his email, theres all kinds of sneeky stuff, but your best bet is to throw ur cards out there like u have a royal flush and say to him, well r u gonna spit it out or is it gonna get ugly! good luck hon, but my radar says its time for u to look for better days and better lays

dont be a crazy piece of waco like zombie dont follow him around just ask him his face will give him away also if he looks up and to the right with his eyes he is lying it is a tell that he is accessing his creative side of the brain

it really depends - has his attitude changed towards you? Has your sex life changed? is he more romantic to you?

we need more info as to how he treats you, not just what his daily schedule is like, or what you believe it is like ...

Seems like you already suspect what's going on.

follow him to "work" or anywhere else

you should ask him face up if he is cheating
