Marriage is a long path that needs two to walk it together, it seems your husband does not care to walk the path .. have you lost hope?

Have you spoken to him?

Is revenge your only option?

Taking the sort of actions you are speaking about means every one gets hurt and end of the relation with no hope of remedy .. are you ready for this?

I feel you need to reflect on the issue with your self, decide on your course of action and then go with your plans knowing you will not live to regret your actions.
