And it's doing my head in.
We were very good friends (or so I thought) until about a year ago. We live opposite each other and our DCs are friends at school and in the same year groups. A year ago, for no apparent reason she stopped replying to my texts, walking past me when she saw me out, sometimes with a half-smile or a quick 'hi' and generally being very 'off' with me for no reason. I asked her several times what the matter was, was she ok, had I upset her and she replied 'no of course not' but carried on being cold with me.
I decided that if she was going to be off with me and not have the decency to tell me why, I wasn't going to lose sleep over it and just carried on saying hello to her when I saw her and eventually she seemed to get over whatever it was and was all friendly towards me again. I did keep a slight distance from her though, ie I never let our friendship get as close as it had once been as it had been ruined by her behaviour. However I do still want to be 'friends' and get on as we are neighbours and our DCs are friends.
But in the year since, she has done the 'off' thing with me several times. Each time she has an 'off' phase I just carry on saying hello to her, at the moment I am getting ignored again. She is on my FB friends list and when she's blowing 'hot' with me she comments on everything I say/do on there, not that I go on there lots, and is always texting me, up to 10 times per day. Then in her cold phase she ignores things, doesn't wish my children a happy birthday if their birthdays fall in her bad mood time, and doesn't contact me. Last year she decided two days before my birthday to be in a bad mood again and cancelled coming on a birthday lunch with me and several friends, giving no reason, just an abrupt 'not coming' text.
To add, she is very attention seeking and likes everything to be on her all the time, I wouldn't go as far as to say a drama queen, but getting that way. I have given up on the friendship but it does upset me a bit how sometimes she is all over me and at other times she looks at me like I'm covered in poo and goes out of her way to avoid me. I don't make any effort with her now btw, I do reply when she sends me messages and of course always talk if I see her but I don't seek her out to talk to her or instigate any texts etc as I cannot be bothered. She doesn't seem off with anyone else at all, in fact she's all smiles and chatty with others all the time
