A new family moved into our village a couple of years ago; their DCs attend the same school as my DCs, although none of our DCs are in the same year groups.
As the family live a few houses away from my house, initially I was quite friendly and chatty with the mum, and she would often catch up with me on the school run and walk to/from school with me. However on the school run whenever we walked with the DCs, her DD would be unkind to my DD, doing things such as trying to push my DD into the road, and pulling DD's hair. The mum would say nothing whilst her DD did these things. One afternoon the DD pushed DD really hard and DD actually fell over into the road, and the mum said nothing so I said to the other girl that it wasn't very nice to do that. The girl then screamed and cried all the way home saying that DD and I were horrible. That night the mum sent me a text saying that her DD was very upset that I'd told her off, and I sent one saying I was sorry she was upset but that it wasn't very nice of her to push DD into the road!
Since then, the mum has refused point blank to speak to me; I tried on several occasions but she turns her head away and walks off so I have stopped bothering. But since then she has seemingly made a huge effort to befriend anyone that I am friends with.
As I said, our DCs are not in the same school year, but she has recently become Facebook friends with most mums that I am good friends with from the school, and has been doing things such as inviting all of my friends round to her house for coffee, and also standing with them at school collection so that I feel I cannot stand with them. She has had nights out with some of them. And now this week she has started going to a fitness class with another friend of mine. I really do feel as though she goes out of her way to befriend anyone who is friends with me. Another friend is having a 40th birthday day out soon, which I'm going to, and I've now found out that this woman is going on that, too, so I'm going to have to make an excuse not to go!
I feel as though she has deliberately gone out of her way to befriend all of my friends. To add insult to injury, a couple of friends of hers who have DCs in the same yeargroup as her DD both refuse to speak to me too, so it's not even as though I could do the same thing to her friends as she as done to mine!
I know my friends are free to be friends with whoever they like, but the school is big, there are plenty of other mums for her to be friends with whose DCs are in the same year groups as her children, but instead I feel as though she has deliberately sought out my friends out of spite.
