Infidelity in relationships.

I keep watching the Greek programs on Nova in the afternoon when I need to take a break from the Comp and sometimes I also watch the morning show.
Was I mortified at the fact that so many women..yes Us Women are unfaithful in relationships and it is growing day by day. I never did and never will condone men being untruthful and cheating on their partners. I believe if you don't want someone then tell them and then start something new, not do it behind their backs.
One of today's stories was about a guy who was married (He phoned in to tell his story) and his wife first cheated with his brother, then with his best friend. I mean is that a Cosmic Joke or what? The guy said his mistake was giving too much to his wife as she didn't obviously deserve it.
The way the World is going what should we do? Should we just get rid of the Institution of marriage and look at relationships as a fashion item?
Nowadays it's the fashion for young men to go with older women and for old men to go with women their granddaughter's age.
Are the old fashioned values of love and trust going out the window?
I hope not but I tell you what if my Fiance ever cheated on me..I will be packing his bags Mate! I won't sit and be a victim!!! I would give him the space and an ultimatum to choose and only one more chance if he wanted to stay with me.
If there is no trust and mutual respect in a relationship then it is well and truly dead as far as I am concerned. When people say they love someone then they have to give respect as well, love does not exist without respect. Women should not only look at men as to how fat their wallet is and men shouldn't look at women as if they have a sell by date! If they can both change these ugly mentalities we might get somewhere!
Well, that is my rant over, I had to get if off my chest.
