Search Results: ex girlfriend wanting to get back

Me and my girlfriend went drinking with her brother and his friends tonight everything went great until we started to go our separate ways home. My girlfriend got extremely drunk and in the past has severely hurt herself trying to make it back home. So I was walking her home and she's mad at me for mistaking a picture of a girl from a porno in a meme that I could barely even see properly because it was minimised and during the evening I tried to apologise the whole time. But now she wants another after ignoring them the whole evening. So I say no and in turn she refuses to go home until she gets it, even going so far as to sit down on the floor like a child when I said "we'll talk about it tomorrow just go home" so I warn her that if she doesn't want to co-operate I'll just carry her home, obviously she doesn't and is still demanding an apology so I pick her up and she starts screaming telling me to get my hands off of her so I do and she walks beside me instead shouting her head off saying that I'm worse than her ex who never put his hands on her. (He raped her so how she figures that I don't know) Anyway at this point I'm very agitated and I'm having to use threats of telling her family to come get her to get her to walk home at all but I finally get her to the door and she asks again for an apology to which I simply say I gave you one, now go to bed and think about everything you've said and done in the morning.
So my question is, was I wrong in the actions I took to get her home safe to her family?

I went out with this girl I worked with a few times, but stopped seeing her primarily because I need more time to move in from my ex. But I soon found out she still lived with her ex boyfriend, so major red flag.
Anyway, she came and left from the workplace over the next year, and she tried to be friendly with me again once she broke up again with her ex. But I got back together with my ex.
After a while, my girlfriend and I were about to breakup as she was Mormon and about to do a mission and I wasn't Mormon. Then the co-worker messaged me wanting to have sex again before she left to move to a different state.
I refused because I still hoped my relationship would survive. But after a month we were done. I talked to the co-worker for a while until she started going to the Mormon church too, and tried to convert me.
It's been two years, and I since rejoined social media and over the past year, my coworker never came up. I used a different email and everything.

But a few days ago, she came up as a friend suggestion with no mutual friends or anything. She even was the first result if I typed in 'm'.
After a few days she wasn't there anymore. But I'm not blocked.

Does this mean she's now checking up on me?
