There are times when the cracks come out in the open.
By then, you hear about rumors of infidelity and cheating.
If you do confess, get ready for a lot of pain on both sides.
You will hurt your partner, of course, and the person may drop you right there.
But keep in mind that it may be more likely for a person who has cheated before to cheat again.
Assuming that you believe that this person is sincere, this acceptance of responsibility demonstrates a certain amount of self-awareness and is also evidence of a working ethical system.
They may save you from making a bad situation even worse. In almost every case, confessing your indiscretions—whether past or present—is the best option.
Without disclosure, there’s no way for the two of you to move on.
Secondly, don't pay too much attention to the "common" signs of cheating that are plastered and spoken time and time again. A smart cheater isn't going to slack up on sex at home; he'll probably be giving it to you the same as always or possibly even more often. He'll pick up new tricks or techniques from a mistress and use them on you.2. Now, granted, this is something to pay attention to, but it could really be just going out with friends.
Unless your man is a caveman, he's probably smarter than that. If he starts constantly going out with his buddies and develops a pattern of doing so that he hadn't been doing, pay attention.
Whether it was a onetime thing or an ongoing affair, something has to change in your relationship and in your life.
