My girlfriend and I have been in an open relationship for about a year now, and during that time, she's had two other partners. She really feels for the person she's currently seeing, which worries me especially. I essentially can't do anything about it because we had a major fight before which led to me allowing an open relationship for her despite me not wanting it. I love her and would do anything for her, so I let her roam, but I think she's becoming too attached than what I'm comfortable with. She even wants to take a break to see other people, which basically means she wants to try this new girl as her girlfriend. I know I can't change her mind about the break, but is there anything I can do to accept this more? Any advice is appreciated!
