A friend of mine, who is presently in a serious relationship,
received a card in the mail from a guy that liked her. I don't know
if she used to have something going on with him in the past, but
she says she didn't. Anyway, she gets the card and puts it into
her purse to avoid any conflict between them and forgot to throw
it away. She doesn't like the guy who sent it to her, has nothing
to hide, nor did she have plans of calling him. She just wanted to
avoid any conflict between her and her boyfriend because he is a
slightly jealous person. One day her boyfriend claims he was
putting a love note into her purse and found the card the guy
sent her.

He has never put a love note in her purse
before, all of a sudden he puts one there. Should she be upset
that her boyfriend went into her purse or is she at fault? What
do you think?
