HELPPP DATING ISSUES

i need some serious opinions. so in the end of October i broke up with my boyfriend because he “cheated on me” along with other small things that i kept bottled up. i didn’t talk to him for a while and i just recently started talking to him again. all of my friends hate him and want me to stay away from him and call me pathetic and stuff like that for talking to him. my family also says that but in a more supportive way. i honestly don’t know how i feel. i have hung out with him twice since then and i mean we cuddled but like it didn’t feel the same. it just felt awkward. i still love the kid and i always will nothing will change that but i need some opinions on what i should do. i mean i don’t necessarily want to get back together with him but i don’t want him talking to someone else. he posted a pic of him and this girl on his instagram and it crushed me. but i just feel like i can’t bring myself to get back together with him. please help me!!!!!
