If U don't read D writing on the wall then all I can say is wake up bro and smell D coffee else go to ur nearest optician.U say she has cheated you twice wid two different guys. I'd say how wud you possibly know.Just coz U caught her wid someone in her bed twice you peg it at two different men. She cud have been balling a dozen men but was plain unluck to get caught with her panties down..who knows least of all you?
What makes U assume she has turned a new leaf after spreading love so liberally and what makes U think she will never do it again ever? Maybe she has simply promised herself that she isn't gonna get caught again. So if ur ready to swallow the (spanish)fly and accept her back with open arms its your choice absolutely.
Who knows if she is able to say"NO" the next time a local stud wags his jewels at her and lures her into your sack behind Ur back? If U love her soo deeply to turn a Nelson's eye then welcome her back and love her to death so she can no longer be inclined to spread her love..Wishful thinking bro!!
