What Happened to Fidelity?

I was talking to a friend the other day and I learned something disheartening.  A couple we both know aren't as strong as they seem.  He has had an affair and encouraged his friend to do the same.  They are active in church and she is always posting how much she loves her husband and what a great marriage they have.  She has no idea who he really is.  What's even worse is the girl he had an affair with was married to another friend of mine and she left him without saying why.  He doesn't know who she really is either.  These people have children.  This particular circle of affairs just keeps going and doesn't seem to have an end in sight.  What is wrong with my generation?  Why is it so difficult for us to be faithful?  Is infidelity more likely to occur in a small town like mine or is it just that everyone is connected, so everyone knows?  This conversation makes me want to run screaming into the night from my little town.  Just last week I posted about strong relationships and the ones I've grown up watching.  Is it just my generation?  Are we simply that selfish?  Considering that I have strong hopes of getting married and having a family someday, this knowledge is extremely unsettling.  Maybe we just aren't working hard enough.  Maybe my generation isn't putting in the elbow grease required to make things last.  I really wish I knew the answers to this one.  There are plenty of other species that mate for life.  Here are some animals we could learn a thing or two from.
