To know for sure you probably have someone follow him. But, there are signs that suggest maybe.
ask him
this is an easy question: see if he goes places alot and be on the phone too much.
There really isn't a way to know if your husband is not cheating any more. You will need to trust that when he tells you he is not cheating that he is not. Of course, you could hire a private investigator to follow him 24/7.
cheating is doing anything you wouldnt want your wife/husband or girlfriend/boyfriend to know about
You are in total control of yourself and you don't need permission or even to wonder about talking to your husband about his cheating. Let him know what you know and tell him if he continues to cheat you are filing for a divorce. Take control!
she's scared she might not have a chance with your husband again.
No. A husband with a cheating wife is called a cuckold.
Unless you find him in bed with another person, you won't know for sure.
If you have absolute proof that your husband is cheating with this other woman then you should deal with your own problems with your husband first and yes, the other woman's husband should know. This is not an uncommon problem and most people (whether a husband cheats with another man's wife or a wife cheats with one of her friend's husbands) is very common and the victim of the cheating generally does tell the husband or wife that their spouse is cheating with their spouse.
Don't count on dreams with such a serious issue such as your husband cheating on you. The subconscious can pick up many things during a given day or, you even watch something on TV where a husband has cheated on his wife and if you are not confident in yourself you could have a dream where your husband is cheating. If you want to know for sure because you heavily suspect he is then sit down and talk it over (good communication skills.) It is probably not likely he is cheating.
Because you're having sexual intercourse with someone else.
that just means that the lady is cheating on her husband to be with your husband
