Long story short - since my neighbor -let's call her DeDe- moved in a few years ago with her Dh and two DS I have tried really hard to be nice. Not just nice, really friendly. We have children a similar age and I initially thought being both new to the area it would be good to get to know each other a bit.
Soon enough I realised that we were really different people and that she had the tendency to have massive strops and mood swings. She has done a few things that have actually been quite upsetting, like yelling at my builders over nothing (truly nothing), stopped speaking to me over Summer then started being nice again. The list is endless actually of silly, petty things. I just never knew where I stood but have always gone out of my way to be really pleasant despite everything. I think she has a really hot temper which cools quickly which I find v confusing. I never responded just kept things civil.
We have never been terribly social and never had dinner/ drinks out or anything like that, although (this is relevant) last year I did invite her for a birthday night out and she came but after this I never got an invite from her to go anywhere since.
Recently, co-incidentally I have got to know some friends of hers through the school and they have been very lovely to me, we have got quite close and they always invite me for coffee/ playdates etc. Last week I had my birthday night out and together with a small group of close friends, invited these "new" friends who know DeDe. At the start of the week I noticed DeDe was being over friendly, in a quite unusual, full-on way, lots of texts and coming to my door which is v unusual and then invited me out to something next month with her
. She seemed to hint as to what I was doing and it made me uncomfortable that she must have heard through them that I was having this night out and was, trying to make me feel bad or something. I didn't mention it but after the event she has gone back to blanking me, predictably.
I have really been nothing but nice to her, even when it was clear we were never going to be close. To make things more weird I know she had a birthday night out a few months ago, was I invited - no. Why is she doing this?
