text: do you believe once a cheater always a cheater or can ppl change? i just married a man who cheated on his first wife. the thing is he cheated on her  with me.  now i am constantly thinking the same thing will happen to me.  i know i would deserve it if it did.  but do you think ppl change or will he always cheat? only you know what kind of man your husband is, did he feel bad when he was cheating on his first wife with you? did he have any feelings off remorse? yes i do believe 100% that people can change and no not once a cheater always a cheater, people make mistakes we are all human. believe in your man and have trust in him or that will be the downfall of your marriage. good luck
