Men are programmed to look at woman and to think about sex. This guy blurted out what he was thinking of. In one way she can be flattered that she has sex appeal- I know at my age, I am.
I understand that it is hard to get over. The big thing is- she now has to make sure her relationship with her sister is ok.
Get it out- that hey this mistep happened- it went no further- and the plan is to honor the marriage vows. There is no plan to act on sex, or anything even close to it.
She did the right thing- and for that- I dont think she should be punished.
Men are like hound dogs and the species could die out of the drive was not there. Then factor in that he had booze. DING DING DING!
She should not be punished for doing the right thing
