I overheard him saying to his friends I’m ugly compared to his ex. Should I dump him?

We got into an argument
then a few days later he said :
“her sexting game is so boring she's fat”
his friend said “she’s not fat she’s thick she’s pretty as fuck though”
then he said “I don’t even care she isn’t shit compared to my ex”
