DS has been going to a sporting activity for a year. I take him every week, parents are required to stay. There is a core group of kids there every week DS included. As such all the parents now know each other. It's a fairly even split of mums and dads and sometimes their partners.
We sit at the same table, are mostly friends on FB and generally pass the time chatting etc. The coach also talks to us quite a bit and we are all friends with him on FB too. I am the only single woman. They are all married.
Last week I posted something on FB about looking for a recommendation for a decorator. A few of them commented (women included) and the coach. The thread moved on to general chat about the club and a christmas party the parents are planning. At this point it was me, two of the dads from the club and the coach still chatting. The thread went on to about 60 posts, including posts from other friends re the decorator.
Around midnight that night I got an annoymous message on FB from a made up profile. The general gist was that I was embarrasing myself flirting with other peoples husbands, who do I think I am, how everyone was laughing at me and to take a good look at myself.
I didn't reply to the message, reported to FB and ignored. Two days later and DS had his club. When I arrived the coach was very curt with me. Two of other dads randomly sat up on the balcony together and not at our usual group table. One of the other dads came and sat down and said 'oooo whats going on here then, everyones being a bit weird' - he isn't on FB and wasn't part of the thread. I mentioned it to one of the women and she couldn't believe it. She had been part of the thread and told me honestly she couldn't see anything which could be called flirting. I asked another friend who I trust to be honest and she said the same.
Today I was on FB and DS coach posted a link to something at the club. When I read the comments it was clear some of them I couldn't see as there were holes in the conversation but other people referencing them and the coaches wife. I looked for her profile and she has blocked me. So I'm guessing it was here that sent the message.
I now feel really awkward about taking DS back to this group and I don't know what to do. What would you do in this situation?
