It was the 70's - "free love" before AIDS, after the pill set women free to be more like men. And BW lived and worked in a MAN's WORLD.
The heart wants what it wants - and while it seems out of character now (she is 79), she may have been a very different woman (in her personal life) at that time in her life. I think it's the Senator's responsibility to worry about his family and also to deal with the fall-out - for all we know his wife (at the time) and his children may have known about the affair already. I am sure both now look back and wish they had done many many things differently - we aren't always rational when we are in love. We all make mistakes and often the worst are all entangled in "love" somehow. Hindsight is 20/20 and we shouldn't look back too long or too hard - can't go back and change what was - isn't everything a mix of joy and pain in the end anyway?
I think we all make bad choices and do things that aren't rational or "right" - we'd be less than human if we didn't accept that life and people aren't perfect. We don't know that BW didn't LEARN from that affair and henceforth never let herself be in that position again. The worst mistake would be to find oneself in that place, with a married man, or you yourself are married and cheating and not LEARN FROM IT. You can accept the good things you were left with and the memories while rejecting the manner in which they were obtained and at the same time accept responsibility for the pain you caused for OTHERS.
We all WISH we were "better" than the mistakes we have made in our lives. Mother Teresa doubted her FAITH, her GOD and her calling - I am sure we all thought she was "better" than that, perhaps more "perfect" than us. And yet, she thought herself horribly flawed, faced her fear every day and worried that she had somehow made a huge mistake in her life. Soon she will be a SAINT and yet she was on earth, delightfully, beautifully, inspirationally HUMAN - flaws, doubts and all.
Even those we look up to, envy, aspire to emulate are underneath JUST LIKE US. Perhaps they are better at the "mask", more skilled at the "dance" but you might be surprised to find that they too look around and find themselves lacking compared to others. Funny how when we "arrive" at the place we thought was "it" the view from there is still all uphill.
