body language-your opinion?

[ontherio_2000]

so here it is. i've been living with this gal who is 36 i'm 32. i got a solid job(14 years)make decent salary,smart honest, faithful and dependable and supportive. we havent been intimate but 3 times in 6 months, she kisses with side of her mouth and looks away when doing so. i want your opinion-what would you say is wrong? i have mine and proved the theory tonight.
my thought exactly. i found out she was at her ex's house and i've found 'evidence' of her unfaithfulness. she lies about it and i know she knows i know. why do women do this to guys? why do we get hit by society as pigs and women expect us to be open and honest when this "very common" thing is against their 'woman honesty clause'?
one more thing. i pay the cell phone and can look thru the records of who she calls. i'm packin bags and movin out. why women pull this crap?
