Is It Bad To Give Some1 All Of Ur Heart???

I don`t know about u guys, but breaking up sucks. My g/f broke up w/ me a few days ago because she wanted to become more "perfect" for me... I thought that she was perfect... I was really in love w/ her.... I was on the verge of killing myself yesterday, and i would`ve if my friend hadn`t rushed over to my house and talked w/ me... She wants to get back together now... Wut should i do??
