Search Results: having a talk with ex

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 a few times with my coworker in 2015. As promising as the relationship was, I broke it off because I didn't feel I was ready for a new relationship, because I wasn't over my first girlfriend, even though we broke up a year prior.
It became an easier decision when she told me she still lived with her ex. But she made it awkward as hell at work. But she quit a few months later.
Fast forward to June 2016, she comes back to work and she holds a grudge against me. Especially since I got back together with my original girlfriend.
I left in August of 2016 and in in December of 2016, my girlfriend and I were having issues and the co-worker called me up one night, and asked if I'd hang out and have sex with her before she moved home the next day. Even though my girlfriend was leaving for a mission and our breakup was inevitable, I didn't do it.
But in early 2017, the co-worker and I started talking regularly and talked about everything that happened. But then she started trying to convert me to the Mormon church and that was the same religion my ex was a part of and I wasn't Mormon.
I blocked and didn't say absolutely anything to the co-worker from that point on.
Last year, I made a new Facebook, and the co-worker never came up during that time.
Last night, I had this very unusual dream where I met up with the co-worker and we worked things out and all that.
Today, I'm on Facebook and she came up as a friend suggestion, with 0 mutual friends and I used a new email and no phone number when I made this Facebook. In addition to that, all I have to do is type 'n' and she is the first result on my search and I never searched her once.
Like I said, it's been almost two years since we last spoke and she hasn't come up whatsoever in this Facebook 8n the year I've had it.

This has really thrown me for a loop and I haven't even thought about her since we stopped talking.

Is this a coincidence or more than that?
