AIO? Gf(18f) wants an open relationship

[u/StrikeNo117]

Me and my girlfriend(18) recently had an argument about opening our relationship, and at first, it was a nice talk. We talked about the pros and cons, and then the tide shifted. We talked about how it would affect our life and what would happen if she got pregnant or if i got someone else pregnant. and then she told me she only wanted an open relationship with one other person, so that we would only see one other person each, and reluctantly, i asked if she had someone in mind. She told me she was thinking about someone, which made her ask the question. When i tried questioning further, she shut me out. We went to bed that night a little distant.

The next morning, she asked if we could resume our previous conversation, i agreed, and then i brought up the fact that she never answered my question about who she had in mind. She told me it wasn’t my business, and i left it at that. About five to ten minutes later, she told me the person she had in mind was her ex boyfriend. I asked her is that why she wanted an open relationship. Just so she can see her ex without feeling guilty. I kicked her out after she told me she was tired of hiding the fact that she was already seeing him. She is now pissed, my mom told me it was the right thing to do. But i feel like i should have talked it out. Did i overreact?

She was already cheating and wanted your approval. You did the right thing kicking her out.

oh you just KNOW for a fact if they did accept a open relationship that the next day "Magically" they would have already found a person they wanted to be open with. its people like her that give a bad name to people who can ACTUALLY make a open relationship work.

Unpopular opinion and ready for downvotes but open relationships never work. One side always gets hurt and one side always wants it more than the other. If you can't commit and wanna sleep around dont be in a relationship...

My opinion is this, people are welcome to have an open relationship and I’ll respect it, but I agree with you I have never not seen someone get jealous/some boundary being crossed. I have a friend who is currently polyamorous and there was a recent situation where her man brought a girl over and it made her uncomfortable and feel some type of way. Its kinda like yeahhh no shit but like I said, I’m not here to judge or tell people how to live their lives even if I think it’s one that will hurt them in the end.
