Just throwing this out there--- as read in MDLWLY...
You have to ask the questions in a certain way and gauge from the answer.
Men want the conquest. They are going to say anything to get it. They will pick up on your clues on how to answer your question so you will let you guard down to give him some. You may be evaluating him to be a husband but he is evaluating you to see what he needs to do or say to get in your draws.
So for the questions you want to know- ask them unsuspectingly-
For example, you want to know his stance on cheating...
"OMG- one of my guy friends just told me he is cheating on his wife. I told him to be careful, he may get caught and risk losing his family. I wonder if the new woman is worth losing his family over... what do you think?"
His response is going to CLEARLY tell you how he feels about infidelity- it is OUR job as women to listen to his words as they come out (not what we want to hear) and what he isn't saying (body posture, facial expressions, attentiveness). I think far too often, we women get responses that we don't want to hear and file them away thinking we can change the men... meanwhile he is telling us "I am not the guy for you, I am going to break your heart" in his own way.
I personally did that with my ex husband--- he told me clear as day he wasn't getting married until after he been with a woman over 5 years, had a kid and lived together. If I was smarter back then when I met him at 24, I wouldn't be a single mother to our son now. I could have moved on and found someone else more aligned with what I wanted (getting engaged within 2-3 years, getting married, then having a kid, etc). Instead I wasted my youth, my time, and my money and while I got a beautiful son out of it- I would have rather marriage and a family with a man who was mentally grown.
Reminds me of another poster on here---- she was talking about her man and his friend dogging the friend's baby mother out because the baby momma wants to be married, etc. Now while it wasn't her man that was doing it, he was clearly telling her who he was. He isn't above doing the same as well and if she were smart, she would stay on birth control and don't accidentally get pregnant. These men aren't "changing on us" - we weren't paying attention in the first place or just thought "it won't happen to me... he won't do that to me..."
