How to stop coworker from being nice and then rude to me?
At first he we would just crack jokes and it helped the day pass by quickly but now he tells me to be quiet and says he doesn’t care about what I have to say. Even though he constantly approaches me and teases me. He will act nice one day and then switch to being extremely rude. He has also said he isn’t interested in me twice in front of coworkers and customers. Which I never was. I feel he does it to belittle me. I just don’t understand why?
I feel like he doesn’t like me or assumes I like him more than coworker level. So intentionally makes me dislike him? Idk it’s honestly irritating and I am done with this pattern of nice one day and extremely rude the next. The other day he told me “my sister saw you and said you were very pretty and I told her ew why she looks like a sloth” (honestly I think sloths are cute so I didn’t really gaf and give him the reaction he wanted) same day a male customer was asking for my number and he kept passing by and after when the customer left, we were passing by each other and he loudly was like “get tf out of my way damn” from how I reacted he came back up and apologized. But that really just set me off and he later started acting nice but I didn’t care and he tried playing victim saying “oh why are you being mean to me when I’m trying to be nice to you”
How do I stop this crap.
I am trying to completely stop giving him a reaction and not interact with him but it’s a small business and it’s just him and two others. I genuinely like this job but the way he has switched on me and becoming worse is becoming irritating.
