My dad used to go with hookers and im sure my mother knew as he used to love visiting Amsterdam in the 80's. I guess some women just accept that men will get bored of them after so many years.
Really??? You don't know women very well then as most would happily rip your tender bits off if they even thought you were messing around on them. Women tend to feel betrayed, angry, hurt, angry, upset, angry, feel worthless and did I mention angry?
Even if they say they will forgive you, you can bet your arse that it will be thrown in your face for at least a year and probably many more than that. Women forgive but we don't forget.
As for taking funds out of the bank do you not have your own account? If you don't then surely you have enough cash on you to put some away each week although I would suggest having your own account that the wife has no access to so would not know if you had taken funds or not especially if punting as if she finds out and decides to leave/throw you out, she would clear the account out faster than you could blink.
