Hello. I am quite annoyed by my neigbors behaviour. They moved next door to our house couple of years ago, a family with two children. They always kept to themselves, especially the wife wasn't even saying hello. That's fine
A year ago , she stopped DH on the street and told him how her husband left and he moved to the x address and how she now has the kids alone etc. At the time it seemed odd to tell all those details to someone you barely know but I didn't pay much attention
Since her husband left, whenever she sees me on the street she just says a typical hello. Whenever she sees DH she will go out of her way to get to him(crossing the street when she doesn't have to etc) and she talks to him about whatever she can think of, apologising for kids making noise or something that happened in the town, or this and that. Its got annoying because we are a family but somehow she thinks that's its ok to try to get close to him while ignoring me.
Lately she does it even when I am there! Yesterday we were taking our kids shopping and she saw us coming out of the house. She said hello to me and rushed to DH who was standing further and started talking with him .Like I wasn't there at all
I spoke to him today and he said he hasn't noticed. I told him that it makes me uncomfortable and of course he can not control other peoples behaviour but he can control his response. I asked him to be more formal with her because for a year now she is behaving like this. He said that this wouldn't be polite 
but I said that its not polite either to carry on being friendly with someone who acts like this . AIBU?
