Infidelity

Infidelity nowadays seems to be a fact of life. Switch on any soap opera on TV and you will find infidelity. It is a common occurence in today's society, with most people having either had first-hand experience, or knowing someone else who has been the victim of it, but it's not a new development - Albert Einstein for example was a favourite of extramarital affairs! http://news.independent.co.uk/world/science_technology/article1171410.ece
However, I don't understand WHY people just seem to accept it when they hear about people having affairs. They may be shocked when they hear of such scandal, but unless you have been cheated on yourself, or a close family member has, most people do not understand just how destructive it can be - not just for the individual, but for their children and families also.
Reading some of the articles given out in the lecture, I realised that the people who embark on an affair tend to blame their partners for one reason or another; and that affairs generally tend to occur when a couple have been married for a few years, have a couple of young children and the sex life dies down a bit. They may get sexually frustrated and so find satisfaction elsewhere, but this is a problem on the individual's behalf, not the partner's. However, many of the partners of the unfaithful feel like it was their fault they first resorted to having an affair in the first place, as they say they didn't give their partner enough attention, or that their sex drive was lacking, etc.
Personally, I could never stay with someone if they had been unfaithful to me - if they have done it once, they could do it again. You have to have total mutual trust in relationships, and if this breaks down, the relationship has ended. To live in constant paranoia that your partner is lying and cheating is not living in happiness, which is what love and marriage should be all about.
