<human>: Could you distill the essence of the text into 1-3 sentences?

In short, my girlfriend has been under a lot of stress with the amount of studying for finals she has been having to do with her finals. I did not think twice to not tell her about this situation.

My girlfriend has known this "friend" since childhood, but she is a terrible influence. I do not like her in any way, and neither does anyone my girlfriend knows who is remotely intelligent. This girl has already mothered children (and had them taken from her) and is having another offspring. She is also separated from her marriage. In short, she is toxic. But enough about her.

Should I even tell my girlfriend she attempted to reach out to me over social media (note I do not even have her added on any of my social media accounts)? She blocked her so her ex-friend cannot contact her in any way. This is probably not something she needs to worry about because of her studies and recent successes. This person has tried getting under her skin so much in the past and trying to convince her that her current friends have been gossiping about her and she finally decided to block all contact. Girlfriend did well on her finals so I have the option to say something, or not. I really want to just ignore it all. The ex-friend doesn't even live here.
<bot>: Girlfriend's toxic ex-friend tried reaching out to me to try to make up with my girlfriend. I have been pondering if I should tell her or ignore it entirely.
