High school

Ok around may 2019 I was with a guy and there were always rumors about him cheating on me which turned out to be fake but 31 January 2020 he cheated on me in my face so ofc we broke up side note (me,him,and my bestie were all friends and when I told her what I saw she tried to defend him saying I should just get over which I was so mad about and we stopped being friends )Like the next my ex posted something on sc(Snapchat) about me and saying how was crazy and just awful things about me. Also after we broke up he started stalking me like everyday driving past my house blowing up my phone with random numbers it was so crazy but now I’m starting to miss lol I’m tired of being single should I reach out to him yes or no .
