It's okay to cry over losing someone. People change all the time but the worst part of change is when it's a step backwards rather than forwards. You learn to trust someone, maybe even fall in love with them and then suddenly you lose everything and it's painful. It'll eat you alive if you let it and suddenly it changes you. It makes you into someone you never wanted to be, someone you never believed you could be. That right there is the reason to be careful who you let in because you never know how hard it'll hit you once they change or leave...
