There's a lot of ways you can find out if your man or husband is cheating on you. You're the only one that knows his behavior, watch everything he does when his home, especially if he have a cell phone. Cell phone can easily detect if his cheating on you. You will not see it laying around the house, instead he will keep it n his pants pocket and it will be on silence or vibrate mode. It might work but a little impossible, when he takes a shower, check his pants and see if he have it. But like what I said, you can tell by his mood and action when the two of you are together.
