if a man asks a woman what's wrong and then doesn't listen - she is apt not to repeat over and over the answer - but simply retaliate in a simple fashion. no sex for a month. but, if a man is attractive, he can overcome this by taking off his glasses and looking sorry. what's the point. women are always on the losing side. if a man is truly sorry they are forgiven. if they are not sorry and do something again and again, they are forgiven. it is the rare man kicked out on the sidewalk by his wife. but, it does happen. probably because he did not fix the garbage disposal or take out the trash.
the mysterious crimes that happen make it look so obvious. the woman dies falling off a boat. the man dies from drinking a mysterious drink. now what really happened. to find that out, we have to examine phone records. was the number based in florida? was the girl an airline stewardess with no mailing address? was the guy an insurance salesman? i don't know the answers to these questions. i think it is a basic flaw to assume anything and that point blank questions are needed.
of course, going round about the question might be the solution for the liar. but, a person who is interested in keeping a relationship going will probably say 'honey, i have to tell you something. that kiss in the livingroom meant nothing to me (she'll think it's her you're talking about - and then get really mad). imo, the worst thing a man can do is ignore a woman's feelings. if she feels she is not #1 - then she will look for ways to prove it. but, if a man keeps telling her that she is wrong and then proving it by coming home when he can early, giving her a lot of undivided attention, asking her to go with him places, etc. - there can be no doubt in her mind that he's truly her's. phone calls during the day are nice, too. (preferably no female voices in the background)
i would say that from my perspective - if mates spend a lot of time together - there is no time for anyone else anyway. and, if you share everything - you'd know in no time flat anwway.
