How does this happen? How does a married man wake up one day and decide he's gonna start pinin after another woman? You'd have done nothin to encourage this, surely
It's not anything you're doing, it's all about the moid. (I mean, unless you're trying to seduce him, which is very easy to do, but you say you aren't, it would not benefit you to do that, and seems like it would be potential career death for you.)
There's a surprising number of things women can do or fail to do in a relationship that will cause men to justify cheating:
> getting pregnant
> failing to get pregnant
> becoming older
> he gets older
> you earn more than him
> you earn less than him
> you are religious
> you are insufficiently religious
> too fat
> too skinny
> too dumb
> too smart
> too many drugs ("you're out of control")
> not enough drugs ("you're no fun.")
> stress of having kids
> not having kids
> his job stresses him out
> his job is not stressing him out enough so he needs more stress in his life
> Equinox gyms (I swear half the people there are cruising for an affair more than they are there to work out.)
> fire alarm battery needs replacing and the beeping is annoying him
> did not renew his vehicle registration in a timely manner
> excessive spending ("what are you, Cleopatra?!")
> insufficient spending ("what are we, churchmice?!")
> preparing salmon too often
> he saw another woman somewhere
> you tried to trim his nails and he doesn't like it when you do that
> withheld treats
> asked him to "go to place" when he didn't want to (these last few are shared with pitbulls)
... so basically anything you can imagine, a man can use as justification to cheat.
