Thank you, kind Internet stranger! I understand your points and I'll certainly take your advices in consideration, but I don't think I'm ready for a step as important as therapy is, at least not now. I feel like I shouldn't take things lightly but also that I shouldn't rush for a solution either, I'm still fully aware of what's going on and I think I'll be able handle it. Fortunately I have good friends whom I can rely on whenever I need to talk, even just to vent, and I know that therapy is very different from that, but I just don't think it's necessary (for me, at least). As for my problem, as I said I'll try and slowly but steadily detach myself from her, and particularly when I go out with friends etc., beyond repeating my points to her in case something like this happens again, even with less of a gravity, in the hope that maybe she can change, acknowledge my independence and stop bothering me with this nonsense. We'll see how it goes. And seriously, thanks again for replying, it means a lot to me.
