My ‘friend’ at work won’t leave me alone. He’s asked me several times to hang out to different places, which I say that I’m not really interested or busy and he won’t get the hint that I just don’t want to hang around him. He compliments me, tells me i’m beautiful, tells me how great I am, asks me how my mental health is going which I feel is weird and personal talking about. He asks so many questions about myself all the time. I believe he thinks we are almost best-friends, but I’d consider him to be just my coworker. Sure, I’ll talk to him at work because I work with him, but I’m not interested to be his friend. I feel a little guilty, but what do I do?
