If cheating is a crime in marriage, why cant we make it a punishable crime in society? Ok, enough about my personal hangups.
Trust and Honor. Hmmm a part of the marriage vows you both most likely said the day the two of you were married, and I believe should be in the back of our minds when we tell someone 'I love you'.
No quick response or easy feel good wording will provide you with the golen answer you wish to hear. I don't preach counseling, but I am going to pull that card now due to the severity of the question. To save this marriage and to start rebuilding trust in the relationship, the TWO of you should seek marriage counseling. I would bet your husband pleads to you his affair is over. If you give your marriage a 'Mulligan' what is stopping him from thinking 'Hey, that was easy.... I need to make a call on my cell from outside' Getting my point? You are setting yourself up for another emotional breakdown. Marriage counseling with a board certified counselor will start both of you on the right path to trust and honor each other. If your husband feels a counselor is a waste and not worth the money, then ask him if he thinks your relationship is worth it -
I wish you and your husband good luck and remember; You only get out of a relationship what you put into it.
