This guy likes me and he’s been flirting with me and he just walks up to me sometimes and just tries to touch me in some type of way and I really don’t like people touching me and I also have a boyfriend.. how do I get this guy to lay off.

Today he walked up to me and kinda pushed me and I said ‘Can you not?’

update—

he did it again today and I ended up texting my friend and she told me it was harassment so i text him and told him basically to lay off and i also text his gf.
