Bit of a long one but looking for some advice. My DS went to a local school for a while and made friends with another boy there. All normal, met the mum in the play ground, talked a few time, exchanged numbers and had couple of play dates. She said he child was autistic and had ADHD, no problem, our kids are friends and they have fun playing together but after a few times things didn't seem to quite feel right. Her child was a handful and that is okay but some of the things he said and did didn't sit right. The mum told me that the school was out to get her and thought she was a problem and didn't believe her son had ADHD, she told me social services were involved and that they doubted her too, she would get very animated about how she was a victim of everyone's misunderstanding her and that so many people were out to get her. She also fell out with a lot of the other parents at school. I felt more and more uncomfortable and eventually I asked her to please leave us alone and stop coming over. I didn't want to be mean but I was very uncomfortable with her and didn't want to leave my child with her or have her round. She left in tears. I felt bad but thought that was it. Not long after she turns up at my home and says it is an emergency and could we look after her son, I didn't feel comfortable but she said she had to take her older child to an interview and there was no one else so we agreed. After that she kept trying to arrange more play dates, inviting my son to birthdays parties. I declined, politely. Then she cornered me in the play ground and said that I wouldn't let my child play with hers because of her mental illness (she says she has BPD) and that I was discriminating. The truth is I think she has zero boundaries and I don't want her looking after my child. At this point I wrote her a long text message, I stated that I wanted her to stay away from me and my child and that I was blocking her number and wanted her to not contact us again. After this every time she has had the chance she comes over to my son and tries to engage him. She has gone up to him in a play park when I was a few meters away and given him sweets, offered to buy him a toy and when I said that was not appropriate loudly exclaimed to my now upset child that she was 'so sorry he couldn't be bought the toy' She saw him on another occasion and offered him a games console which again I declined which of course upset my son. My son is 10 and I am now afraid to let him play in the park with his friends unless I am actually standing within 2 feet of him because she will approach him if she catches me not looking. Yesterday I was in a shop at the counter and my son was looking at things on the shelf, she came into the shop, saw him and started talking to him about her sons latest diagnosis and saying how much her son missed playing with him. I know I can't stop people talking to my child when we are out and about but honestly I am getting super creeped out. How can I stop her? Or am I being unreasonable? It is not a 10 year olds job to put in the boundaries with an adult and I can understand why he would find the idea appealing if being offered sweets and toys and games consoles, he also really liked her son and would like to play with him again but I really don't feel safe around her.
