Search Results: dealing with an ex

I have written a question about this topic before but need different advice. Months after I saw my ex I l saw him staring at me just like he did before (Blank facial expression, only looked away when he had to turn a corner). Now rather than finding out why he is doing it I just want it to stop. Keep in mind we have both moved on and are both currently in relationships. But I don't get why he did it again since it has been months since I last saw him. I'd figured he would try to avoid me as much as humanly possible. I know I am going to bump into him again which is why I rather resolve it but I am not sure how or if it's even worth it.

Please if you have detailed suggestions send them my way. It is pretty creepy, strange, and uncomfortable dealing with it.

My husband and his ex have a beautiful 8 year old together (little curly to the far right) so that means there is quite a bit of communication between us. Here’s my issue. She’s constantly ugly to me, but kind of in an inconspicuous way. For instance, she’ll tel me about their past sex life, but follow up with a “oh, but I’m sure y’all’s are great too” she lied about him proposing multiple times and said she keeps all her engagement rings from him in a keepsake box. (They were 19, there were never multiple rings) she even went as far as to bring me a photo album of them when they were dating and asked me to put it out so *child* can be reminded how much they used to love each other when he comes over. I️ never know how to react to all of this because i don’t want *child* Sensing any tension from us and upset him. It really hurts because I’ve been nothing but nice to her and I absolutely love her son, but I think what she’s doing is inappropriate and for whatever reason, aimed to really hurt me.. how would any of you handle this? It’s out of character for me to scream or cuss at someone and i also have the kids to think about so i need to tread lightly.
*also don’t make fun of the pic. It was Christmas and the kids’ idea lol*
