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

My GF was showering while I was on her laptop, so for some reason I snooped, I am not proud of it but I did. Backstory: She dated this very abusive guy for 6 years from the age of 16-22. He degraded her, ruined her self-esteem, cheated on her and told her many times, but for some reason she stayed with him for 6 years. She told me she was completely over him after their nasty breakup. Anyways on her history I found out that she regularly searches him up on facebook and about a month before we dated she was helping him with resumes and stuff and calling him my love in the emails. 

Is this a red flag? If she said she was over him 5 years ago, why would she call him my love? Is it possible she may still have feelings for him? How do I bring this up?
<bot>: I think gf may still harbour feelings for ex, still called him my love right before we dated, and regularly searches him on FB
