That being said, once a partner has cheated there are still a lot of issues to deal with. Just breaking up isn't always so easy. Sometimes people want to stay together even through hard times. Unfortunately for most people, once trust is lost it is not easily regained.
This loss of trust leads to suspicion, jealousy, arguments, and often the "break-up-make-up" routine. This happens because both people still want to be together even though one (or both) of them cannot get over the past. Getting over a betrayal is very difficult, especially if it comes from someone who you really care about. This is the time to ask yourself an important question. "Can I forgive them?" Put all the reasons, anger, and intricacies of the problem away and ask yourself that one simple question. If the answer is yes, then you have something to work with. However, if the answer is no, then it is time to part ways. What happens often is the answer turns out to be "I don't know." Take some time, and think it over. Just don't put it aside and pretend that there isn't a problem. Those feelings won't go away unless you acknowledge them. No relationship works without trust, and no relationship works with grudges.
A moral for all involved:
Before you break a promise, evaluate how important that relationship is to you. If it isn't important enough to keep, don't be in the relationship.
If you broke a promise and are now regretting it, make your intentions clear. It is going to take hard work and time to get that trust back.
If you're trust was broken, take some time to think it over. If you can find it in you to forgive that person, there may be hope to restore you relationship. If you can't, don't waste your time (or theirs) trifling over problems that you won't ever fix. It is time to move on and heal.
