Hi Nanamar ,
Sadly, you can't really do anything about it .
Just remain pleasant and friendly and avoid a row or confrontation .
I moved away after knowing a neighbour for three years .
Initially , she told me that she found her previous neighbours too much and she didn't want to be friends with me .
Then , when I moved she was devastated .
And then ,the nastiness crept in .
When I phoned she'd answer and walk away from the phone whilst she talked to other people .
I'd be hanging on for ages .
After some years , she began an affair with an old flame and used me as an excuse - telling her husband that she was spending weekends with me .
I didn't actually know .
When the guy became serious - she ditched him .
When her husband found out - he blamed me for encouraging her affair .
And that's when she told me that she couldn't be friends with me anymore because her husband wouldn't like it .
This continued for about a decade whereupon she began to contact me again .
I can't stand her moods anymore .
I've made better friends .
