Mitzik your story is so sad! I have "pet" spiders in my house too.
False widows are quite safe for most people, a small number of people are allergic (like wasp stings). But they aren't going to pounce on you as you walk past. I too have been bitten when i accidentally picked something up with one on in the garden, it was like a pin prick (not painful, just an ow) and i saw it scuttle off. If my history is right, they've been around since victorian times so nothing to worry about.
