Grannylin, glad to know that your husband is still well. We had a terrible dispute about our hedge in our last home, and at one point husband was sent to hospital with a suspected heart attack - false alarm, I'm glad to say. The hedge dispute escalated into an awful war of attrition (mainly on the part of our neighbour) and although we moved away two years ago, DH still feels anxious in case we meet neighbour when returning to our old stamping ground. Situation led to legal bills, etc., and I have read of murder being committed over a boundary dispute in the past!
Glitabo, do you have a caring friend or relative who would approach your neighbour in a friendly way and ask them if they are aware of your difficulties, if you feel unsure about doing so yourself?
Good luck with this difficult situation, I really sympathise.
