I will TRY to shorten it. I started at my current agency in November 2018. I made a few friends including a guy in a unit around the corner. No problem, I like work friends. Eventually we exchanged numbers (fast forward: huge mistake). Keep in mind I'm happily married, not looking to date; simply exchanged numbers for work/friendship's sake. He would bring my other (female) coworker and me little candies and things, as a nice gesture perhaps. I ended up transferring to a unit upstairs this past August. By that time, his visits and popping into my office randomly had started getting on my nerves. (It was an open cubicle.) Here, I have a large office with a door. So anyone coming in has to knock. He will text and ask about coming to visit at a certain time (WHY a physical visit is so necessary, I have no idea). I blow it off with I'm busy, I have a lot to do (which I do) or just ignore completely, to which his response is to suggest a later time OR just pop up anyway. It's to the point it weirds me out, and not only that but my conscience is bothering me. If my husband was texting some chic at work, I would not be ok with it. That was my mistake thinking it was gonna be an innocent coworker phone number exchange. Without going to HR because I don't want him in trouble THAT way, what do I say to politely tell him I appreciate the gesture, with the candy he leaves in my office (creepy in itself since he comes into my personal space to leave it here) but I can't (and don't want to) deal with these visits and texts? He isn't like a forceful, arrogant dude. He is very polite and mild mannered, but I also wonder if something is a little off upstairs, not trying to be mean. I just don't want him pestering me anymore and I am too nice and patient and hate being mean. I am transferring to another unit; I applied for 2 different positions over there, just waiting to hear which one I got. One is behind a closed door, the whole unit is, and he actually got bummed and upset that that one is behind a door and "I know it's selfish but I won't get to see you now".
