Honestly maybe but why would you want to go back with someone who lied to you about emotions played you for months and shows no remorse for leaving you for another guy? There are a million what if's but I'd call you an idiot if you went back with her. She clearly has played you. Movre on trust me there are a million better woman out there to give love to who will in return give it back to you and instead of using you. Stop wondering one day you won't want her back and for good reason.
