My dear, when a marriage breaks down, it effects everyone. Your troubles are not unique. But if the only thing that you can think of is revenge, then you need a serious reality check. I guess sensible advise to refrain from revengeful behavior is not going to go down very well with you at this stage. But sensible behavior will benefit you in the long run, by helping you to build a new life elsewhere. But if revenge is what you wish to pursue, then be prepared to dig two graves. One for your husband and in-laws and one for yourself. Revenge and the bitterness will change you in ways which a broken marriage will not. It will poison your thinking in ways which will destroy any chance of future happiness that life can offer you.
God be with you.
