I think im falling for this guy, He says hes falling for me too, but hes a player..and i have trust issues?

Help? He acts like he loves me, and he tells me im the only one, but ive been cheated on waaay too many times..And i reallly want him too be different, but idk if he will cheat on me or not...I dont trust guys easily, bc my heart has been broken sooooo many times. I really dont think i could take it again. He plans to ask me out soon, Should i say yes? and take the risk? Or say noo..and stay friends? bc Honestly guys, they can be amazing and treat yhu right, but wit my luck thr usually all cheaters): I just hope hes a guy thts worth my time....Help?!
