Boss' Husband Is Stalking And Video Recording Me While She's Out On Vacation. In Colorado.

Long story short, my boss has taken to hating me the last 6 months. In November she pretended to write me up but I've never received a copy or had a copy uploaded to my employee file when I only had 5 days to appeal it. I've been going along with her game, came back into the office full time which is so dry that I actually damaged my cornea. She then took this to HR saying I fell asleep during a meeting when I was just closing my eye because it was in so much pain and was already on prescription drops. She then also has been suddenly saying the way I dress isn't appropriate when I've been dressing the same way for over 2 years straight. And to top that off, over a teams call, she told me that she believes the LGBTQ community is brainwashing children via teaching high school kids about sexual identity and orientation and drag queens reading books in libraries when she knows I'm a member of that community. I don't want this to turn into a political post so please don't focus on that debate. To the current situation: She went on vacation with her son and left her husband behind starting last Wednesday. When I came back into the office on Thursday, her husband who works in another department was hiding in this corner with his phone out like he was waiting for me to come in cause after I walked by, got my tea, and got to my desk like I always do, he took a lap to the other side of the cubicles from where he sits to look at me again. Come today, guess who walked past me on my way in and instead of going to the front door he b-lined back to his desk which was behind where he was going? Immediately, he was sitting back at his desk texting when I walked by on my way to my desk because that's in my normal pathway. I feel like I'm being harassed and stalked at work. Not only by my boss but now by her husband who just happens to also work here and I never ever used to run into.

So, onto the questions: 1) Is this viable workplace harassment? 2) Is he allowed to be video recording me without my consent in a Healthcare workplace with his phone? 3) Isn't this workplace retaliation from my boss by her obviously telling her husband HR sensitive topics and employing him to stalk me while she's out? 4) What are my legal courses of action since I feel completely unsupported by my company despite the fact that my team of 8 people say that I'm a good leader and great at what I do? 5) Really any advice is helpful. I'm job hunting but I want to know if there's anything I can do to protect myself from losing income until I can get something new...
