<human>: Today I dropped the bomb. After dating for 3 months, I told her that I no longer want to be in a relationship with her. I told her that it was because I need some time to work on my shit (Depression and anxiety of which she is aware, and is supportive like nobody I have ever known). At the moment is seemed like the right thing to do. Hindsight being 20-20 I think I just got scared and ran. Things were getting serious and I freaked out and made a brash decision. She loved me and I loved her. She still loves me and I still lover her. I feel like I made a HUGE mistake. I feel like I should have just sat down and worked out some boundaries and talked to her about my feelings. I told her that I wasn't going to close this book and put it up on the shelf not to be opened again. I don't know what I'm doing and I don't know what I want. I do know that the last thing I want to do is hurt her, but I did and I feel awful. I want her back but I feel like too much of a scumbag to tell her that i made a mistake. What do you think I should do? What are your thoughts about what happened?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Broke up with her because I got scared. Now feel like I made a huge mistake and want to get her back but I feel like too much of a scumbag to try ad get her back.
