When you are caught cheating, and wanted to save a marriage that is important to you, you need to accept the fact that you would be sitting on a hot seat for quite some time. This means that you own up to your mistakes. How do you do this? The first thing you need to do is, of course, apologize from the deepest bottom of your heart. When you apologize, take responsibility. Never insert an iota of excuse, in other words, never blame your partner for your infidelity. Then, make a condition, or ask your partner what you need to do to prove that you are sincerely sorry. This could be tough, because this would mean that you would be living worst than the dog on a leash, but if you need to get back on that nook, you have to do, what you gotta do. Next, be honest no matter what it takes. This is the moment when even one trivial slip can cause a major aftermath and might cause your marriage crumbling down into the office of a divorce lawyer.
The next step is, do not wait to be asked. This means that you call ahead, buy flowers ahead, and think what it is you need to do to make your partner forget the excruciating pain you have cause. This may come is expensive packages sometimes, but it will be worth it when you are trying to save a marriage without trust.
