Hello mate,
I understand the pain that is accompanied by unfaithfulness in a relationship and I am really sorry for what took place. I personally believe that being in a relationship or marriage needs commitment, communication, understanding and, above all, love. Whenever any of the four misses, then there must be a problem in the marriage or relationship. I feel that whatever made your husband to cheat on you is because either of you failed in any of the four above-mentioned aspects. I understand you are in a painful situation but don’t give up on him just yet. Try to communicate with him to find the base of the reasons that made him cheat on you and try to come up with the best solution. You might find that maybe he never intended to hurt you and might be apologetic. If so, forgive him because we all make mistakes and no one is perfect.
Cheers!
