Would you want to know if your husband had done these things and would you blame the woman in this scenario?
If he:
Became friends with a woman over 30 years younger
- Started messaging said woman at all hours, even when she didn't reply he would hassle with follow up messages
- Asked said woman to meet up for lunch (which she went to as friends)
- Asked said woman to stay over at your house while you were away for the weekend (which said woman refused)
- Kissed said woman against her will and touched her inappropriately
- Told said woman he loves her, that she's the most beautiful woman in the world and he wishes he had met her 30 years ago and could marry her
- when said woman told him to leave her alone, he sent constant messages asking why and declarations of love
Assuming you are in your 50s/60s you want to know, or considering said woman is not going to have an affair with your husband would you want to live in ignorant bliss and have an easy life?
