One of the first things to seriously ask yourself now is -
do I still want to be with my husband?
If The answer is yes, then You have to go through this - and ,get over it.
You say you've talked with him about it - so !! are you feeling better?
Sharing your burden with others helps - like on the curezone - but only temporarily
You can't change him - because nobody can change anybody else,it's not possible -
He might do it again,he might not - nobody knows,not even him I imagine.
But for you to live in the fear that he might have sex with another woman is like rust,it will slowly eat you up.
But luckily,change can happen - to you!
The way is not through positive thinking,or visualization,but by watching,(not controlling) how your mind and emotions work, on automatic "in spite of yourself",it's the same for all of us
We're provoked,by whatever, (in your case your husband had sex with someone else)our button is pushed,and off we go automatically,usually very
similarily to how our parents,or "role models" would react.
You have the power to change things only by being aware,not by blindly ,repeatedly making the same mistakes twice, or more.
Consolation for yourself,or putting him down is just a quick fix - if you want to get to the root (of how You got to this point in your life,not how he did this to you ),look at Your behaviour, not his,non judgementally,impartially,as if watching someone elses' home movie - it's not necessarily about who's "wrong" really,it's more about,this happened ,now how are you going to turn it to your advantage,or not
we often can't decide what happens to us, but we can always decide how we respond,if we're willing to.
The learning never ends - because we all make mistakes
Or, if you decide you can't tolerate his behaviour,dump him,just don't drag it out.
Being in a relationship is usually where all of us learn the most about ourselves
If he's not the one you feel you want to learn with,and love with ,move on !
