breakup tips..?

i just broke up with my boyfriend and i did really care for him. i cried for endless hours yesterday. but i had too bc he was really toxic, he would body shame me and all that kinda stuff and he was controlling and hypocritical.. i feel really torn up and i keep wanting to text him and go back even tho my parents hate him and everyone i know is telling me not too. and i know i shouldn’t i just need ways to keep myself from doing so and help moving on.
