My ex reluctantly left a few months ago as he was emotionally abusive and controlling, and hurt the children more than once. He rents a shared property around the corner and over the road (bit too close for comfort, but at least he's not in the house).
I was concerned he had access to my phone somehow, he knew things I'd talked about in private etc and he's extremely tech savvy (part of his job). So I bought a new phone and haven't connected it to the house WiFi, which he still pays for. Now he wants to install an antenna on the outside of my house so he can access the WiFi at his new place. He needs a good connection for wfh, and says the Internet at his new place is rubbish (we have the fastest you can get here). He won't ask his landlord about upgrading or moving his contract over there, claiming it would require the house to be rewired.
AIBU to think he wants access to spy on me somehow or am I being paranoid? When I asked him who the internet was with the other month he claimed he couldn't remember, and I don't have the password to access it (my laptop and the TV etc are already connected so I only ever ask for it if I have a guest who wants to connect, and he never tells me).
