Answer:
Well, at times you can see they are acting a little weirder than usual. Other times we can't tell if our spouse is doing something behind our back, because of our daily life and routine. To others there are some signs that we can tell, it doesn't matter if were smart or not,still we can see the difference, but no one thing: no matter how long your spouse cheats on you, the secret won't be a secret forever. You will hear soon enough.
ANSWER:
Most of the times us wives will never know if our husbands has extra curriculum outside the marriage. I guess we can say the trust that we gave to our husband are real and strong. It happened to me a few years ago, and he also open the incident that he did before we got married " lies and his betrayal."
Anyway, my trust for my husband for many years was real, even though he never made time for me, yes I gave myself some excuses why he can't make time for me, especially after he retired from the Navy. He promises a lot to me to what I need to expect when he retired from the navy, " that it will be my turn and only me" but unfortunately it didn't happened. Broken promises, no times, and always busy is what I received from him. Until one day 2006 when I discovered his love affairs with a married woman. They met on a dating site, and from there he started from being friends who visit her at work late at night. Who went to the beach late at night so they can be together alone. When his home he will lock himself in his office and talk to her on the phone till early morning. When he gets up in the morning, the first thing he does is call her and listen to her voice. Every single morning from Monday to Friday this is what he do, talk for 2 hours sometimes less. This are some of his action that I noticed and he also admit to me that he fell in love with her. So the day he told me his feelings for her, that's when I knew that my life will never be the same anymore. I asked him to go back to her and never come back. And I divorce him the same year.
