Put a post it note in the spot where he leaves the candy that says, "I am a diabetic and I am allergic to YOU. But thanks for doing your JOB. HR here I come!"

He's clearly interested in working on more than your computer. Workplace romances are tricky, so if this is not something you want, be clear wit him.

I think you meant declining instead of deciding. And if you're single you might consider being nice to him.

It Sounds like he likes you

He likes youuuuuuu.
This is so cute
Like plant one on him 💋

He’s sweet on you

Yup. Sometimes we guys need something very direct.
