Should I take him back?

me and my boyfriend broke up last week cus there where rumors of him cheatin on me, I know I shouldnt had believd them but I did. now im mad at my self cus I didnt have any proof that he did it. the girl he supposily cheated on me was his ex, she and her friends were the only ones sayin that he cheated on me with her. I didnt hear it from no one else. when we broke up he got relly mad at me, and now hes going around telling everyone how much he luvs me and how much he wants to get back with me. he called me like 3days ago and told me how he felt. I mean I still luv him in every thing im just confused on what I should do. im just afraid that im going to get hurt. what should I do and do you really think he cheated on me?I kinda think he scared of his ex lol, sum people say that he could b using me, but I dont see how cus he got a job, and he know I dont feel comfortable givin him money lol and he cant use me to have sex cus I told him from day 1 that I wasnt ready for that so, and he cant use me just to have a gurlfriend because if that was the case then he would b with his ex right???. and on top of that if he didnt care about me he wouldnt b all up on ma pu**y all day errday, callin me tellin people to talk to me. I just need yall opinion on what yall think and what should do
