I got mad and texted my girlfriend A lot. Vented to her with 17 texts. I was so pissed because she just ignores me. So Girlfriend dumped me. I was being needy, but she was not there for me anyway. At all. She said: You are single now, if you meet someone then it was meant to be. She said: "I won't date anyone, I have no time for that. If we are meant to be, the relationship will rekindle itself in a few months. This is healthy"

Then she said, we can text and still hang out. Then retracted the hanging out part. Said: I will be too busy with my new job.

She is so consumed with her job!

What should I do?

1. Learn a lesson about texting and being obsessed

2. do not contract her again and find someone new to date.

First off you need space in a relationship to keep it healthy and your over texting wasn't letting her breathe.
Just give it sometime and if you guys rekindle feelings its meant to be and if not then its best to let her go and find some one new :)
