Breakup advice💔😭

Im 17 he is 18 We were together for 3 years, he was 14 and i was 13 when we started dating.. And now everything is over😭 we had many many ups and downs and not to lie he made me the happiest.....but he would also bring me down and was almost never there during the times i was broken and depressed.. I broke up with him because i found us always arguing and fighting over simple simple things and i couldn't handle being mad all the time.. Once i did he saw that guys started following me on Instagram and immediately assumed i broke up with him to "hoe around" and that supposable I just played him😭😭😭

How could he think i would use 3 years of my life dong that? I tried explaining that to him but i was furious because he started caling me a hoe and all these horrable names.. I just dont know how to deal with the breakup.. He was the only person i had.. I have no friends because of my anxiety 😭😭

Its 4:18 and I've been up until 2:00 just crying my eyes out.. I haven't been able to sleep😭 i miss him because i would always try to see the good in him and I'm still trying to but i know my worth😭😭
