sillysally: I was thinking about this after reading the Jon and Kate thread, but didn't want to hijack it....
Do you believe that a spouse can be driven to cheat by their partner, or is that just an excuse for betrayal?
A partner can be made unhappy or unsatisfied by the actions or non-actions of their loved one, but cheating (physical infidelity) is an action taken by choice. No one can take over your brain or body and MAKE you do something dishonorable. You CHOOSE to turn outside of your marriage to make yourself feel better or to find the love, affection, attention or sex that you may or may not be getting inside your marriage.
My ex had a huge laundry list of reasons and excuses he gave for cheating but when I tried to end the marriage numerous times (before I knew he'd been unfaithful) because neither of us was happy and couldn't seem to fix it, he held on for dear life, didn't want to end it, etc. Even once I did know and was adamant about ending it, he still tried to talk me back, WTF? He just wanted to have his cake and eat it too, wanted to maintain the facade of the happy family man while getting his strange on the side. Uhh, not.
If you're so unhappy in your marriage that you need to go outside it to be happy, do the honorable thing and end it, then go get someone else, not the other way around. I hope that's not what has happened with J&K+8, but if he has cheated, she's better off without him, regardless of what a shrew she is or isn't. No one DESERVES to be cheated on.
