Hi I dont know if yall remember me since I havent been on in months!!! Well my name is belinda im 16 no kids and im from tx

well I was in arelationship for about 3 1/2 years and we broke up for about 8 months and recently one of my friends died right before grduation and I guess that made us both think and we got back together well it didnt last because he would always tell people when we werent together who he would sleep with and then I asked him and he denied it to me and the only reasson I thought I had aright to know was because someone had told me that he had said he had gotten a deasise from his ex and I thought I should know well I dont like being lied to so we broke up. Well during the 8 months we werent together his family would not leave me alon (chase me down the street I got my car keyed, practicly I couldnt go out) well since we broke up again its started all over y cant they understand they cant force me to be with him what should I do????
