Nope, just from my unintentional 1 time experience - (Very long read):
(I knew enough not to get involved , emotion/sex wise, with someone fresh out of a relationship. I really, really liked this guy and had a major crush. Hard. Still, I figured I could compose myself enough just to have conversations, texts, movies/beach/dinner, etc.)
He didn't talk about his most recent ex until one day he asked me why was I was available/single, yada, yada. So, I asked him in return, making conversation, and he just said he loved her, it wasn't reciprocated, he's tired and he was ready to move on. Cool...but not enough for me to dive in & throw caution to the wind.
One morning, I go skipping my happy tail out to my car and some strange woman is standing there. I wait because she's standing in between my driver's door and the passenger door of the car parked next to mine. She's not moving, just looking dead at me. So, I say excuse me. She says are you so & so? I say yes, why? Who are you? She says I'm so & so's fiance. Are y'all dating?! Did you know about me?!
I ask her what she's doing at my place?! Her lips are moving but no words come out - The girl just starts sobbing - it was ugly. I just look at her. Then I get the daily 'good morning, beautiful' text from him and she stops sobbing long enough to ask if it's him? I don't answer because I didn't even get a chance to look at the message and I wasn't going to take my eyes off of her. She then ask if I can do a 3-way call but begged me not to say she's on the other end and that she would mute her line.
I told her that I would do her one better - Delete & block him and told her not to come to my place ever again. Got in the car and pulled off. She was still standing by that car sobbing when the guard gate rolled back and I looked in the review mirror.

When he couldn't reach me after awhile, he'd pop up unannounced (most likely tailed another car into the gate) but I would just look at him through the peephole. He came by my work only once - (You have to buzz at the gate, then say what your visit is for, then sign in at the front desk and wait. I never came to the lobby.)
One day, his 'fiance' calls my phone to say she's not calling to start anything but knows that he is still trying to contact me. And that as a woman I should understand her feelings. And for me to keep my word. I hung up and since I now had her number, I blocked her too.
That was too much drama for me.
I really, really can't fathom why/how that guy thought he could get away with anything with her on his ass, lol.
