^Just imagine... her:DH are you coming to bed? Him: in a minute I'm chatting to x.
Her: let's cuddle and watch a movie.
Him: ok. , but spends the whole time on the other end of the sofa tapping away^
Seeing as the wife told OP, a year ago, that she wasn't happy with her DH anymore, I very much doubt she's been asking for cuddles in the two weeks OP and her DH have been communicating.
I generally agree with PP, it would be weird if my DH started confiding in another woman suddenly, however OP has known him for 10 years so it's not a new friendship.
Surely if a friendship has lasted 10 years and still going, then opening up about something as big as a marriage break down is normal?
In any case, why is it that the wife is perfectly reasonable for spilling about her marriage a year ago?
OP has said several times that they have been communicating for two weeks, yet marriage seems to have been ending for at least a year.
OP, if they're both friendships that you value, and you know this the case for sure and not just someone shit stirring, then I'd ask her - not him - directly.
There could be many reasons she blames you. As a pp said, she could suspect an affair, and you being a close friend, could be the no1 suspect.
She could have even said 'he's been more bothered about Florence with 'NameChanged' than listening to me' and whoever she has said it to has taken it to mean more than it did.
As you can see from this thread, there'd be plenty of people who would find your trip to Florence sinister, so I wouldn't be suprised if another friend has even put an idea into her head about it.
Or he could just basically have found misplaced feelings for you, which have occured during a year long marriage breakdown and he's told her at some point.
If you really want to know, you'll just have to ask her. If you ask him, and he does in fact have feelings for you, he could not tell you the truth.
