NO!!!!
dont dump him !!!!
I went through the same thing
dont he doesnt deserve it he likes you
and if your dealing then he likes you too never
leave the innocent of the cheaters...
Trust me hun i did it and i regret it more than anything...
well my dear, it is pretty hard getting over an ex. but there was a reason why you && him arent together. if he didnt hurt you before, you wouldnt be with someone new. my advice is, dont go back to the one who hurt you. instead care for the one who cares for you now :)
