<human>: Can you give me a shortened version of the text?

Last night, my girlfriend of two years broke up with me because she saw I was following a girl on Instagram and I supposedly lied about following her.... About an hour or two later she called and texted me crying for me back, but the thing is, the more I think about it I don't want to be in a relationship anymore. I haven't been personally happy in a while and need some changes in my life and I think this is one of them. How do I let her know that she's a great girl and it's not her fault but I think I need to move on?
<bot>: GF broke up with me but now wants me back, I don't think I want her back. How do I let her know it's because of what I want not because of her?
