hey OP... i've been cheated on by a bunch of chicks! I've learned a few signs of cheating...

trying a new move in bed... isnt one.

if she is constantly texting and being discreet about it... and acts startled when you walk near her while she is doing it.

or always running late coming home from work...

or has to up and leave for work in a hurry multiple times in a short period... during her non typical hours...

business trips that are shady... as in she never used to go on them...

has sexy underwear that you havent seen her in, after quite a while of owning them...

expensive jewelry that she never wears... and the origins are unknown to you...
