Advice?

Okay so me and this guy had Been messing around for two years off and on I broke up with him the first time because I randomly ended up with chlamydia, he tried to tell me it was some type of bacteria and that he had messed with anybody. after our two year anniversary I found out that he had been cheating so I broke up with him for the second time. We still talk on a daily basis but I don’t want to be with him because the simple fact that he cheated and he lied to me for about a year. So there is this other guy and I started talking to him but then I kept hearing a rumors so I left them alone then I started talking to him again he’s a good person he makes me smile and we always have a good time he even brought me over to meet his mom. and he doesn’t seem like all the other guys like the type of guys that just want sex, but you never know nowadays but I don’t want to get cheated on again that doesn’t feel good. So I don’t know if I should work things out in try to get over the fact that I was cheated on or should I just start over?
