I moved to a new apt about 2 weeks ago.

My neighbor downstairs in very nice, but he's a guy and I think he might like me and I do not feel the same way. I have taken a liking to him as a person. But that's it. We've had some nice chats. He's younger than me by like 7 years or so.

I feel that I am struggling to be assertive since I moved. Its been a stressful experience learning how things work around here, and some things my landlord wasn't upfront about. There are some maintenance issues too. This was my second move in 6 weeks. I'm staying put. Its not bad and my landlords been a combo of nice and not. But mostly nice. I'm just struggling to be assertive with them too.

Back to my neighbor. A week ago we were talking and he confided in me he left his job. He was feeling crappy about it. I was on my way out the door when we were talking so after listening I said I had to go but that "my door" (metaphorically speaking) was open if he needed to talk. He seemed to take it literally and I was too shy to correct him and taken off guard. I wished I had not said that. But I felt so awkward saying "I have to go, I'm on my way out." And kind if guilty. And wasn't sure what else to say. I know it was a mistake.

I also get a weird feeling from him. He is a nice person but from the day I met him I noticed he looks me up and down. Tonight, about 8:30, he knocked on my door. I didn't answer right away. I was in my,pj's and had a low cut shirt on. Definitely not expecting company. I also had to put my mask on bc I don't want him or anyone besides my parents in my covid bubble. I talked to him thru the door first and he said I had some mail. It turned out to be from census, and for his apt, which I told him but he insisted it was for my apt. Ok whatever. I also got that weird feeling from him again so I thanked him, said have a good night, and shut my door. Also he doesn't typically wear a mask around me...

I'm not sure what to do. Or maybe I am. I know I messed up saying "my door is open if you need to talk." I changed my mind. People can change their minds. He seems like a nice guy and I like him as a person. But should I maybe not answer my door if he does that again? Should I not be as friendly? I dunno. I think I should be myself. But I don't have to open my door. Though he does not seem like a threat. But yeah.
