Should i forgive? Can i forget?

This guy didn't sound like a winner BEFORE I read he had cheated on you recently...so were it me; his a$$ would have been dumped long ago. His needy/"leave me alone" episodes serve to keep YOU off balanced and chasing after him. This guy is likely also a potential stalker if you ever do get a backbone and break up with his sorry a$$, so if you do, take precautions beforehand, because he will be SO SWEET and likely seem like everything you want if you are shutting him out, but I guarantee, if you were to take him back again, it'd be the same old tricks. Don't let two years of your life turn into a decade, or more. Drop this turkey COLD now. Remember, YOU choose your life.
