Put this on your other post.
Since when does a cheater who walks out on you and shacks up with his "lover", get to decide when HE is coming back. What about "sorry", remorse, repentance, or does he not have a clue on what he did meant to you?
NO was good in reply to his pathetic text, and now you can put other things in place to stop all their calls and txts completely. Contact your phone carrier and get them blocked, get a new number, or ask them or police to contact him and tell him to quit all contact or he will be charged with harassment or whatever charges may apply.
Whatever you do, do it for you and your peace and contentment and leave the two nutters to stew in their own juice.
God bless
