What should i do stop talking to him or try to work things out?

okay so we been talking for a while but we argue too much and and we don't seem to go to another level he says he loves me but i don't think its true and sometimes he's so sweet but then he s a jerk and like a week a go we got in this huge argument and i told him for us to just stop talking and we did till today he text me and told me that we should hang out and then he mistakenly text me the wrong message saying another girls name with hearts and i made him confessed that he was going out with her
