Today, my girlfriend broke up with me because I was, "trying to change her." A week ago I asked her to stop talking to the 6 guys that have all previously asked her for nudes. FML
While I get that it makes OP uncomfortable, I don't think anyone ever has the right to prevent their SO from talking to someone. I mean, sure, OP can explain why it weirds him out, and ask why she would even want to keep talking to those guys, but it's up to the girlfriend to decide what she does with that. If OP literally told her to stop talking to them, I understand that she wanted to break up.
#26 I take it you'd be fine with your partner sending nudes to almost ten people then? Because hey, you don't have the right to tell them not to, right?
As a matter of fact, yes, I would be fine with that, although I would probably advise him to take care with sending nudes as you never know where they might end up. But that's my personal opinion, and I get that everyone has a different comfort level with regards to this type of thing. That's why it's important to discuss boundaries when starting a relationship. If OP is uncomfortable with his partner talking to people who are interested in her in a sexual way, that is definitely something to discuss with her. However, it sounds like OP simply told her she needs to stop talking to them, which seems controlling and unhealthy to me. There is a big difference between "you do this thing that I'm uncomfortable with, can we talk about that and see if we can find a solution that works for us both?" and "you do this thing that I'm uncomfortable with, and I've decided on my own that you need to stop doing it".
#22 And she did nothing to discourage them, AND kept talking to them all. Most people in a normal, stable relationship would call that a "warning sign".
Wth?!! Sorry OP. It ought to be standard girlfriend protocol to do that without being asked to. Sounds like you are better off without her and her many admirers.
