My girlfriend and I had a long argument. We fell out of love. But still love and care for each other?

broke up w my gf ..my best friend. We had a loving relationship for 3 years. However, in the last year things got rocky bc she had exaggerated her ual past with men. It turns out that she is a v insecure person in r/ships & also had troubles relating to my ity (she is lesb). I found out she been cheated on twice and her parents dumped on her when she came out. over a year, she kept telling fibs ab things she had done w men to relate to me & impress. I was annoyed and wanted breakup.She begged me and said she will change.So b/c we were best friends, I hung it out.Tried to understand.But at same time,my anger turned to judgement. I started to not trust anything she said, and judged her past. I fell out of love-but loved her.This caused bitterness and the argument took a huge toll..exhausted her. 3 wks ago, she said SHE had fallen out of love and the argument played a part. She wanted out. BUT Im over the argument & my feelings for her returned- bad timing! can it be reversed?
