A very good friend and former work colleague (male) died of cancer about a year ago. I became quite close with his wife as she dealt with his terminal illness which happened very quickly in the end over a 7 week period and supported her through the immediate aftermath which became very complicated due to issues with his family. We've met up a few times since but although I have offered support (they have young children) along with a few other work colleagues/friends she's not really taken it. She's a very intense person and obviously the stresses of the last year have taken their toll. I sent her a text message a day after the first anniversary of his death. She sent a couple of very very rambling texts which I didn't reply (and did the same to my other colleagues) to which she followed up with a text a week ago. I didn't reply immediately , I felt I wanted to give my reply some thought.
Last night she sent a Facebook message and a couple of texts asking me to contact her immediately about something serious. The last time she did this was when she found out her husband's cancer was terminal.
Then she followed it up with a few more very long messages saying that she didn't need to talk now but basically saying that she had been told that her husband was having an affair, I replied saying of course he didn't - he loved her and the kids and I was with him all day at work and knew he didn't have time to! She then sent a further message which basically spelled out that I had been implicated in this and pretty much she was asking if we had a relationship. She didn't believe it but needed to put her mind at rest and someone was shit stirring.
We definitely did not have a relationship, he was my boss for most of the time we knew each other. We were very good friends and met up for lunch/coffee etc more so after he was diagnosed with cancer. He visited me in the hospital after I had my twins early.
I am stunned that anyone would think that anything untowards was happening - we hugged a few times when we met or said goodbye when we met up outside of work but that was the limit of any physical contact. It was purely platonic. He did the same with others.
I'm concerned about two scenarios, either someone (I can't even imagine who!) has made this up to hurt her or she has made the whole thing up. I have of course told her that nothing ever happened and that we were only ever very good friends but I was concerned about who had put this in her head and wanted to talk to her. Our mutual friends are my work colleagues or ex work colleagues and two of them are in senior positions where I currently work.
I'm just very confused about how to deal with this situation.
