Thank you. Hearing this really helps - I know that natural I'm a people-pleaser and I'm terrified of any behaviour that might be 'rude' (like not asking questions back). She's taken advantage of that and used me for a long time. I came to realise that she only gave me the cat in order to keep something over me - problem is, now I'm really in love with the little fella and could never, ever give him back (she also didn't take great care of him). Hoping your method works a treat!
So I sent a cat picture to the crazy stalking ex-neighbour with some generic message of everyone is doing well, enjoying the last of the summer. She responded normally - said she's glad he's happy and wishes me all the best. All good and peaceful.
Today I see she's tagged me in a comment on Facebook. She had found me on Facebook when she lived nearby and I had, stupidly, accepted the request (back when she seemed relatively normal). She began to tag and send me 6, 7 memes a day - to the point where I had to tell her several times I just don't use Facebook, I don't check my messages, I'm not on often. I set my account so she wouldn't see when I was online (I call/message my daughter using it so I am on a lot).
The comment was on a post of a complete stranger to me, she'd shared a 'happy ginger cat day' post. The crazy neighbour commented saying she's so very very sad that I don't realise she needs me to reach out proactively rather than her asking for updates and it breaks her heart after she 'entrusted' the cat to me. She tagged me in the comment.
I'm honestly speechless - I answer every message she sends, but I don't reach out spontaneously because quite frankly she's easily encouraged and her behaviour is quite scary (she's previously turned up at my door uninvited). She reads into everything and wants us to be best friends. I'm scared of proactively messaging because I don't want her to think I want more of a relationship.
I've explained why I'm scared to go no-contact before considering she knows my address and legally I'm not quite sure where I stand with the cat (and there's no way I'm giving him back). But Jesus, what would you do???
