Thanks Hops,
I can’t afford a security system, though mounting a fake camera might work. Even with that, my Co-F feels that he’s above the law when it comes to his children. They’re his kids, he owns them, and he can do as he pleases. He has disregarded, and even laughed off, our requests for privacy thus far.
There IS a very good chance that the package was delivered by him, and not SIL. Even if he’s too old to drive safely, he’d do it anyway if given orders from his queen. Where I worry about SIL is what might happen in the future, now that we’re living closer. NM knows exactly how to “work” SIL, push her buttons, and get her fired up enough to act out. The threatening emails I received all contained information from my childhood that only NM would have known, so she evidently gave this information to SIL, taunted her with lies about me, and got her fired up enough to compose those emails. Since my brother is the golden child, NM thinks his gun collecting is “cute.” She isn’t connecting the dots to any threat. She's completely oblivious to the fact that it’s also a threat to HER, as SIL hates everyone in the family (everyone on earth for that matter).
All that being said, I’m still hoping that this cancer NM has had for years is real, and perhaps just a slow growing type that has been over exaggerated as “a month to live” for four years and counting. I hate that I’m wishing death on someone, but it’s the only thing that will end my own suffering. I may try emailing a cousin who I haven't talked to in years to find out what he knows about this "terminal cancer." If she goes, the harassment goes with her. I just wish she'd die. I really do.
