<human>: Give me a shortened version of the text

I'm starting to feel a little bit better about my break up 4 months ago. However, I struggle to stop thinking about whose fault it was  and so I begin to shift the blame to myself almost every time. I should probably add that this was my first relationship and hers too.

She had broken up with me because she said she didn't have the time. I accepted this at first despite still feeling a little hurt. But about a month or two later, I found out from a friend the real reason she didn't want to be together anymore (big mistake, I know) and it was because she thought I was too clingy and she  didn't want to deal with that. I was afraid of this exact thing happening since I worried that I wasn't giving her enough space, but she always said I was and I was fine.

Assuming it was my fault for it ending, how can I forgive myself or stop beating myself up about it? It's difficult for me to accept that I repulsed someone so much that they wanting nothing to do with me anymore, despite how much I wanted the opposite.
<bot>: Girlfriend broke up with me because of something I did that she did not like. If it is my fault, how do I forgive myself and if it isn't, how do I stop blaming myself?
