any advice ?

i’ve been with this guy for a year and i thought everything was great even though there were some red flags i was genuinely happy but then this girl reached out to me that he had been liking her pictures secretly and i kept finding out more and more about him lying and i was still talking to him but kept my distance to find out he lied about going to a strip club he’s such a bad person but i felt attached in a way but i seriously need to let go and move on but im really upset where its really starting to affect me even though it seems like he doesn’t even care any advice for moving on ?
