it's okay to get hurt sometimes.. u just need to figure out if it's worth it.. someday someone will be worth it if u put up walls.. u can't love, right?
You can't prevent yourself from getting hurt again unless you stop getting into any love relationship anymore. And besides if you have this auto-defense up and become super cautious/suspicious towards your new partner, it's gonna be a huge turn-off.
there might be some truth to this... reflect on yourself, did you do anything wrong? or just the wrong person? if you don't taste the bitter how do you know what sweet is?
maybe the guys you went out with were nicknamed "dumpher" haha! I think pain is a healthy thing. It keeps you thinking. Questions like WHO WHAT WHERE WHEN HOW WHY ?? WHAT DID I DO!! TO DESERVE THIS!!!!! haha
