Iwant my ex husband back i want to diss him what should i do how can he come back?

If you feel the need to do that than it sounds like you still care for him or you would not be wondering what you could do to hurt him like he apparently hurt you. Don't lower yourself to his level- it isn't worth it & trust me getting revenge will not make you feel better in the long run. The best revenge you can have is to move on & have a happy life. Take care!
