Search Results: how do i break up with someone

I broke up with my ex-girlfriend about two months ago, but I continued to live in her house. She's started seeing someone, which I think is fine, but she asked me a few days ago if she could bring that person home, and I said it would be too uncomfortable. A few days later she brought someone round, came into my room at 4am drunk and said she was at home with someone...

If you were my ex-girlfriend, would you have done what she did (especially when we were trying to finish as friends)?

And what would you have done if you were me, knowing that she was having sex with someone in the next room?

I have an ex right before I met my wife and after we broke up I deleted every pic I had of her and moved on. A couple months later my ex and I broke up, I couldn't stop thinking about her so I looked at her IG and she posted pictures that I had taken of her. Every few month since our breakup, I get bombarded with thoughts of her and I look at her social media and I see pics of places we've been together or pics I took of her. I don't think she wants to get together and I got over her fairly quick. I married someone this year that is perfect for me and have even stranger and stranger connection. I've thought about my ex twice since we broke up. The first time was on my birthday a couple months after our breakup and an hour later she wished me a happy birthday. The next time was yesterday when I saw a YouTube video showing a destination I went to with my ex and it was all the same places we visited together wo I started thinking about her and the places I visited with her. An hour after watching the video, she messaged me. I don't have the impression she wants to get back together but the connection we have is weird.

My wife and I have an even stronger connection. We've had people over to our house and for some reason I felt the need to food. Ten minutes after I did that, my wife asked me to order food and every time I've ordered, it's been from the place she's thinking of. This happens all the time and it's like we're in sync. But it gets even weirder when she starts answering questions that I've got in my head and before I can even ask, she's already answered my question, When I ask her about this she says that she knew what I was thinking. When we were long distance, she said that she could always feel me next to her. She always struggled being clingy and thought that was why she was single but when we started dating, she felt that I was always there and it cured her clinginess.

I'm curious if anyone else has had someone show up after you've thought about them.
